Porsche Suspension Packages Explained: Dundon Setup, Track Day & MCS 3-Way Guide

A Porsche suspension upgrade should not start with the question, “How stiff do you want the car?” The better question is: what is limiting the chassis right now?

For some cars, the limit is factory alignment range. For others, it is rubber compliance, front-end precision, tire wear, rear stability under power, curb behavior or damper control at track speed. A 992 Carrera, 991 Turbo, 718 GT4 RS, 997 GT3, 991 GT3 and 992 Cup car do not need the same suspension recipe. They have different factory hardware, different tire loads, different alignment windows and very different use cases.

That is why Dundon Motorsports suspension products are built as systems. The goal is not to make every Porsche harsher. The goal is to give the car the right geometry, the right connection and the right damping for the way it is actually driven.

The two systems: setup packages vs Dundon-spec MCS dampers

Dundon suspension products fall into two practical categories. They work together, but they solve different problems. This distinction matters because many owners try to buy dampers before the chassis has enough alignment range, or they buy adjustable arms when the real limitation is how the car moves over curbs, under braking or through fast transitions.

1. Suspension Setup and Track Day Setup Packages

A Dundon Suspension Setup or Track Day Setup Package is about geometry and connection. Depending on the chassis and package level, these systems can include control arms, camber links, toe links, titanium tie rod ends, caster-adjustment components, shim kits, sway bar end links, rear dog bones and spherical-bearing upgrades.

In plain English, the setup package controls where the tire points and how consistently it stays there. It opens the alignment window so the car can run the camber, caster and toe settings that actually work for the tire and use case. It also reduces the rubber deflection that makes a car feel vague when it is loaded hard.

This is the foundation for better tire wear, sharper steering, more front grip, more stable toe, cleaner corner balance and better confidence. If the car cannot hold the tire where it needs to be, a damper upgrade cannot do the whole job.

2. Dundon-spec MCS Suspension Packages

A Dundon-spec MCS Suspension Package is about damping and motion control. The dampers are built by Motion Control Suspension to Dundon specification, then paired with the supporting hardware and spring package appropriate for the chassis.

An MCS package controls how the car moves: braking support, pitch, roll, curb response, bump compliance, transition behavior, tire contact and consistency over a full session. This is where the car becomes calmer, more tunable and more confidence-inspiring at speed.

The best builds often use both: a Dundon setup package for geometry and connection, and a Dundon-spec MCS package for damping and spring control. One fixes the alignment and mechanical interface; the other fixes the car’s motion.

Basic, Intermediate, Advanced and Pro explained

The package levels are not a generic “good, better, best” ladder. They describe how deeply the system changes the car’s geometry, compliance and alignment authority. The exact parts vary by chassis because a Carrera, Turbo, GT4, GT3 and RS car do not start with the same hardware.

On Carrera and Turbo models, the first meaningful step is often about correcting the narrow factory adjustment window. On older 996 and 997 cars, the problem is often a combination of limited adjustment, aging rubber and a desire to bring the car up to modern tire expectations. On GT and RS cars, the factory platform is already more serious, so the package levels focus more directly on track alignment, rubber removal and consistency.

Availability varies by chassis. For example, some Carrera and Turbo packages are built around Basic, Advanced and Pro logic. GT4 and GT3 Track Day packages often use Basic, Intermediate, Advanced and Pro because the track-use progression is more defined. RS and Cup cars may have narrower options because the factory platform already starts at a much higher performance baseline.

Why Dundon-spec MCS 3-Way is the main damper path

For most Porsche owners looking at a Dundon chassis package, Dundon-spec MCS 3-Way is the main damper answer. It is the no-compromise version: better than stock street ride when properly specified, with the precision needed for track use when the car is loaded hard. Dundon provides the recipe, setup sheet, baseline guidance and support to get the car squared away.

The reason is separation. A 3-Way remote-reservoir damper gives separate control over high-speed compression, low-speed compression and rebound. That matters because a curb, a pothole, a braking zone, a fast transition and a mid-corner platform issue are not the same suspension event.

• High-speed compression influences curbs, bumps, broken pavement and sharp impacts.
• Low-speed compression influences pitch, roll, braking support, corner entry and mid-corner platform control.
• Rebound controls how the spring and tire recover after inputs, transitions and surface changes.

This is why 3-Way is not just “more knobs.” It is more precise control. The car can gain support without simply becoming harsh, and it can gain compliance without feeling loose. That is a major advantage for Porsche owners who care about both road quality and track performance.

Dundon provides the parts, the setup sheet, the baseline guidance and the chassis-specific recipe. The owner is not left to invent an alignment or damper setup from scratch. We also teach you what each adjustment does, so the system starts from a known point and can be refined around the platform, tire and use case.

Where does MCS 1-Way fit? On selected 911 applications, MCS 1-Way is the budget-focused version. It can still be a quality damper upgrade, but it has less capability because it does not give the same separation of impact compliance, platform support and rebound behavior. The 3-Way is the no-compromise path: better street refinement, more precise track control and straightforward ownership because Dundon supplies the correct setup sheet, baseline recipe and guidance on what each adjustment does.

For Cayman and Boxster applications in this guide, the MCS recommendation is 3-Way only. The mid-engine cars respond extremely well to the additional control and refinement of a proper 3-Way package, whether the car is a road-focused build, a street/track car or a more serious track platform.

I street drive my Porsche. Why would I want a 3-Way setup?

Street driving is exactly where refinement matters. Real roads have expansion joints, uneven pavement, potholes, driveway transitions, surface changes and high-speed sweepers. A simple damper often forces one compromise: add support and the car can feel busy; add compliance and the platform can feel loose.

A Dundon-spec MCS 3-Way package gives more precise control over those different events. High-speed compression can help the car absorb sharper road inputs. Low-speed compression can hold the chassis up during braking, turn-in and acceleration. Rebound can be matched to the spring so the tire stays connected and the car feels settled.

That is why a 3-Way package can ride wonderfully on the road — and, when properly specified, can ride better than stock while giving the driver more control. It is not a track-only punishment. Properly specified, it gives a high-quality Porsche more polish, more composure and more precision while still giving the driver the adjustment range to support track use later.

The key is that we provide the recipe. You receive the parts, the setup sheet and the chassis-specific guidance to put the car in the right window. We also teach you what each adjuster does, so you are not buying a box of adjustable parts and guessing where everything should go.

Detailed chassis-by-chassis guide

987 Boxster / Cayman / S / GTS / Spyder

The 987 platform is light, communicative and rewarding, which is exactly why its factory limitations become obvious when the car is driven hard. The usual problem is not that the car needs to become brutally stiff. The problem is that the factory alignment range and factory rubber do not always support the tire, driver and track use the owner has in mind.

A Dundon setup package gives the 987 a more useful alignment window and a more connected mechanical platform. That matters for front-end response, tire wear, confidence on turn-in and consistency as the car transitions from braking to corner entry. The car feels less like it is moving around underneath you and more like the tire is doing exactly what the steering wheel asks.

For a street-focused 987 that sees occasional HPDE or canyon driving, Advanced is usually a strong path. For a more serious 987 build, Pro makes sense when the owner wants the car properly prepared around sharper tires, more aggressive alignment and less compliance.

A good 987 setup should feel natural, not overbuilt. The car responds best when the alignment window is opened first and the suspension is allowed to work with the tire instead of fighting it. That is why the package logic starts with the pieces that give the shop real camber and toe authority, then moves into more complete compliance reduction when the driver is ready for it.

The buying decision is simple: choose Advanced when the car is still mostly a street car that sees spirited use and occasional track days. Choose Pro when the car is becoming a serious driver’s car and you want the chassis refreshed around modern tire grip, sharper response and a more durable alignment baseline.

981 / 718 Cayman and Boxster S/GTS

The non-GT Cayman and Boxster platforms are naturally balanced, but they still need geometry and damper control if the owner wants the car to behave like a serious performance build. The mid-engine layout rewards a precise front axle. When camber, toe and damping are not right, the car can feel good at moderate pace but start to use the tire poorly as speed and load increase.

The setup package addresses the foundation: alignment range and connection. The Dundon-spec MCS 3-Way package then controls how the chassis moves under braking, rotation, throttle application and rough surface changes. This is a strong combination for owners who want a Cayman or Boxster that still feels refined on the road but becomes more stable and confidence-inspiring at the track.

For Cayman and Boxster applications, our MCS path is 3-Way only. We do not position 1-Way as the recommended alternative for these cars. The mid-engine platform benefits too much from the additional control, precision and refinement of the 3-Way package.

The practical pain point on these cars is that they can feel excellent on the street while still leaving performance on the table at the track. The car may rotate well, but the outside front tire can still be overloaded and the alignment can still be too conservative for the tire. The setup package helps the mid-engine platform use its balance instead of relying on that balance to hide the limitation.

For a customer who wants to buy once, the better long-term path is setup package plus Dundon-spec MCS 3-Way. The geometry lets the tire sit correctly; the 3-Way lets the driver tune support and compliance around road use, HPDE, tire compound and future pace. With the Dundon setup sheet and baseline recipe, this is a clear and manageable system rather than a guessing exercise.

981 / 718 GT4, Spyder, GT4 RS and Spyder RS

GT4 and GT4 RS cars reward precision. Small changes in front grip, camber, caster, toe and damper behavior can significantly change how the car rotates, how confidently it accepts trail braking and how consistently it uses the front tires.

The Track Day Setup package is staged so the owner can match the build to the actual use case. Basic is for the first serious track alignment. Intermediate opens more adjustment range for aggressive settings and track tires. Advanced removes more front-suspension rubber and gives the car the sharper steering response many GT4 owners expect. Pro is for the owner who wants front and rear alignment authority and less rubber left in the system.

GT4 RS needs the same logic, but with higher stakes. The car is faster, more intense and more loaded than a standard GT4. Here the goal is not to make the car feel “sportier.” It already does. The goal is to keep the tire working, keep the platform calm and give the driver more confidence when the car is loaded hard.

Dundon-spec MCS 3-Way is the damper path for this family. It lets the setup separate curb and bump response from braking support and mid-corner stability, which is exactly where these cars can benefit on track.

A GT4 driver typically feels the limitation at corner entry and mid-corner: the car is capable, but it wants the front tire, alignment and damper control to be matched to the pace. A GT4 RS raises the stakes because the car carries more speed and more load. Small setup mistakes become more expensive, and the driver needs the platform to stay calm when the tire is heavily loaded.

For GT4 and GT4 RS, the package level should be chosen around tire and usage. A first-time HPDE owner does not need the same parts as a driver on slicks or aggressive 200-treadwear rubber. The value of Dundon’s staged approach is that the customer can start with the alignment pieces that matter first, then move into more complete front/rear control as the car, driver and tire package become more serious.

996 Carrera, C4/C4S, Turbo, GT3 and GT3 RS

The 996 generation is now old enough that suspension upgrades are often both a performance improvement and a chassis refresh. Even a well-kept car can be working around aged rubber, old alignment assumptions and tire technology that has moved far beyond what the chassis was commonly set up for when new.

For a 996 Carrera, the value is front-end precision, more usable alignment and a more modern feel without losing the character of the car. For C4, C4S and Turbo models, the added weight, power and rear load make stability and compliance control more important. For 996 GT3 and GT3 RS cars, the goal is to preserve the raw character while giving the chassis the alignment authority and damper control needed for modern track use.

On selected 911 applications, MCS 1-Way can make sense as the budget-focused version when the owner wants a quality damper upgrade with less capability. Dundon-spec MCS 3-Way is the no-compromise recommendation for a 996 that sees sticky tires, repeated track sessions or a driver who wants the car to ride with real refinement while feeling controlled and precise rather than merely firm.

The biggest mistake with 996 suspension is treating every model the same. A rear-drive Carrera usually needs precision, tire support and a modern alignment window. A C4 or C4S needs the same foundation with more attention to the front/rear balance. A Turbo needs rear stability under power. A GT3 or GT3 RS needs the car to retain its mechanical character while becoming more consistent under modern track loads.

This is also where a package saves time. Many 996 owners can spend money replacing one worn component at a time and still never create a coherent suspension system. Dundon’s package logic gives the shop a defined path: refresh the weak points, open the alignment window, reduce the compliance that moves under load and choose MCS 3-Way when the owner wants modern damper control without losing the reason the car feels special.

997 Carrera, C4/C4S, Turbo, GT3 and GT3 RS

The 997 is one of the most communicative modern 911 platforms, which makes suspension tuning especially rewarding. Carrera models become sharper and more precise. Turbo and C4S cars gain rear stability and confidence under power. GT3 and GT3 RS cars gain better tire use and more repeatable track behavior.

The setup package gives the chassis modern alignment authority. That means the car can run the camber, caster and toe it actually needs instead of trying to make a factory adjustment window cover a much more demanding use case. The deeper packages also remove rubber where it matters, so the car feels more connected and more stable when loaded.

On selected 997 applications, MCS 1-Way is the budget-focused path for owners who want improved damper quality with less capability. MCS 3-Way is the no-compromise answer when the car sees sticky tires, repeated track use, high-value street/track driving or higher driver expectations. On 997 GT3/GT3 RS, the FAL-compatible options also matter because fitment and hardware need to match the car.

For a 997 Carrera, the most noticeable gains often come from front-end confidence and tire use. The car becomes easier to place, less vague at the initial turn and less dependent on driving around the factory alignment limitations. For Turbo and C4S models, the rear of the car becomes the priority: power delivery, weight and tire grip make the rear suspension work hard, and the package helps keep that load under control.

A 997 GT3 or GT3 RS customer usually knows what the car should feel like. The suspension package is about getting there with less compromise. Intermediate is the first serious correction, Advanced gives a more connected front end and Pro is for the owner who wants the whole front/rear system addressed. Adding MCS 3-Way turns that geometry foundation into a damper package that can be tuned for tire, track and driver preference.

991 Carrera / S / 4S / GTS

The 991 Carrera and GTS cars are fast, comfortable and capable, but they are not GT cars from the factory. The limitation is not basic chassis quality. It is the alignment window and the amount of rubber compliance left in the system for a car that may now be running more tire, more pace and more track time than Porsche assumed for the average road car.

The Dundon setup package moves the car toward a more serious performance platform. Better front bite, cleaner turn-in and more stable alignment are the main gains. When combined with MCS, the car also gains better control over braking support, roll, transition behavior and bump response.

On selected 991 Carrera applications, MCS 1-Way is the budget-focused damper path with less capability. The Dundon-spec MCS 3-Way package is the no-compromise recommendation for owners who want the 991 Carrera/GTS to feel much closer to a purpose-built dual-use car while still riding better than stock when properly set up.

A 991 Carrera customer often wants GT-like precision without turning the car into a single-purpose track build. That is exactly where the package logic matters. The setup package gives the car the alignment and connection it needs, while spring and damper selection determine how much track focus is added without damaging the road manners that make the car useful.

The recommendation depends heavily on options and use case. A rear-wheel-steering car needs the correct Pro path. A PDCC or FAL car needs the correct MCS configuration. A canyon and weekend car may not need the same intervention as a car on aggressive tires at repeated track days. That is why we ask for model year, options, tire and usage before recommending a specific package.

991 Turbo / Turbo S

Turbo models need a different lens. A 991 Turbo or Turbo S has enormous acceleration, additional weight and heavy rear load. That makes rear stability, bushing control and alignment consistency more important than they are on a lighter Carrera.

The setup package gives the car the geometry and mechanical connection needed to match the powertrain. The goal is not just sharper steering. It is keeping the rear of the car composed under power, reducing vague behavior and giving the tire a more stable platform to work from.

For a lightly used street Turbo, a setup package can be enough. For an owner pushing a Turbo hard enough that power, tire and weight overwhelm the stock compliance, the Dundon-spec MCS 3-Way package becomes the logical damper path.

The Turbo customer is usually not trying to make the car feel delicate. The goal is to make a very fast car feel more composed, more connected and less vague when the rear suspension is loaded. The stock car is impressive, but track pace, heat, tire grip and power quickly expose how much the factory hardware still has to compromise for road comfort.

This is a chassis where Advanced or Pro often makes sense for serious drivers because the rear of the car needs to hold alignment under real load. MCS 3-Way is especially useful because the owner can add support for braking, acceleration and high-speed transitions without simply making the car harsh. For a Turbo that is driven hard, that adjustability is not a luxury; it is how the suspension keeps up with the engine.

991 GT3, GT3 RS and GT2 RS

A 991 GT3 does not need to be made sporty. It already is. The real question is how consistently it uses the tire and how much confidence the driver has when the car is loaded hard. The Track Day Setup Package adds alignment authority and removes compliance in stages, so the build can match the driver, tires and track use.

For 991 GT3 RS and GT2 RS, the problem shifts even further toward high-load control. More tire, more aero and more speed mean the car needs precision and support rather than vague softness or random alignment movement. These owners usually care less about “does it feel sporty?” and more about whether the car stays calm and repeatable at pace.

MCS 3-Way is the natural damper solution for this group. It adds the ability to tune curb compliance, braking support, transition response and rebound behavior separately. That is the kind of control a GT or RS owner can actually use.

The 991 GT3 family benefits from a staged system because owners use these cars in very different ways. One owner may want a proper first track alignment and better tire wear. Another may be using Hoosiers, slicks, aero and repeated high-speed events. The same chassis badge does not mean the same package level.

This is also one of the clearest cases for MCS 3-Way. A GT3 or RS car already has the pace to expose damper limitations. Independent high-speed compression, low-speed compression and rebound let the driver tune curb behavior, braking support and platform control separately. That is what makes the car easier to trust at the limit instead of merely stiffer.

992.1 / 992.2 Carrera / S / 4S / GTS

The 992 Carrera and GTS cars are extremely capable, but they still start from a road-car suspension brief. The factory setup is designed for a wide range of owners, roads and comfort expectations. When the car sees real performance use, the narrow alignment window and remaining rubber compliance become the limiting factors.

A Dundon setup package gives the 992 Carrera family the ability to run a more serious alignment. That means better tire wear, more front grip, cleaner turn-in and a chassis that feels more connected without pretending to be a GT3. The Pro variants also matter for owners with rear-wheel steering because the rear of the car needs to be addressed correctly, not generically.

On selected 992 Carrera applications, MCS 1-Way is the budget-focused version when the owner wants improved damper quality with less capability. Dundon-spec MCS 3-Way is the no-compromise answer when the car is built for serious street use, street/track driving, track days or any driver who wants better street refinement with the ability to tune support and compliance separately.

A 992 Carrera is fast enough that many owners reach the limit of the factory suspension before they expect to. The car has the speed, brakes and tire potential to run at serious pace, but the alignment and compliance are still set up for broad road-car use. Dundon’s package turns the platform into something more deliberate without pretending it is a GT3 from the factory.

For most serious 992 Carrera conversations, the decision is not “parts or dampers.” It is sequencing. The setup package gives the car the geometry it needs. Dundon-spec MCS 3-Way then gives the driver the ability to control movement around braking, curbs, transitions and tire grip. The 1-Way is the budget-focused version where available, but the 3-Way is the no-compromise fit when the customer wants a real long-term chassis solution with better ride refinement and track precision.

992 Turbo / Turbo S

The 992 Turbo and Turbo S are high-speed, high-power, heavy-load platforms. They are exceptionally fast in factory form, but sustained aggressive use asks a lot from the rear suspension, tires and bushings. The car needs more than a generic “lower and stiffen” approach.

The setup package opens the camber, toe and caster range while reducing compliance where it matters. The benefit is not only sharper steering. It is better rear stability under power, more confidence at speed and a tire contact patch that is easier to manage when the car is loaded hard.

The MCS 3-Way package is the damper path for a serious 992 Turbo build. It gives the owner the ability to tune the car around braking zones, acceleration load, rough surfaces and high-speed transitions, rather than forcing one compromise into every part of the drive.

The 992 Turbo has the kind of speed that makes chassis confidence essential. A vague rear end, conservative alignment or uncontrolled body motion is not just annoying; it limits how comfortably the driver can use the car’s performance. A setup package gives the car a better mechanical foundation, while MCS 3-Way gives the owner a way to support that foundation as grip and pace increase.

This is also why generic lowering or stiffness is the wrong frame for a Turbo. The car needs compliance over real roads, support under major load and stability during acceleration. The package should make the car easier to drive quickly, not simply more aggressive. Dundon-spec MCS 3-Way is the right conversation when the owner wants the Turbo to feel more controlled without losing the qualities that make it usable.

992 GT3 and 992 GT3 RS

For a 992 GT3, the suspension conversation is not about making the car exciting. It is already an exceptional driver’s car. The gains come from alignment range, tire use, curb behavior, braking support and repeated-session consistency.

The Track Day Setup Package lets the owner choose the right level of intervention. Basic handles the first track alignment. Intermediate increases track-oriented adjustment. Advanced removes more front-end compliance. Pro, where appropriate, creates the most complete system around sticky tires, serious track use or aero.

The 992 GT3 RS starts even closer to a race-track baseline, so the suspension package logic is narrower and more targeted. The car is already serious; the goal is to support higher tire and aero loads and keep the platform predictable. A Dundon-spec MCS 3-Way package on a 992 GT3 adds adjustability and forgiveness without treating every road input as a stiffness problem.

A 992 GT3 owner is usually chasing consistency, not drama. The car already has the excitement. What the setup package adds is the ability to put the tire in the right window and keep it there. That shows up as more confidence on turn-in, better braking support, cleaner mid-corner behavior and tire wear that makes more sense after repeated sessions.

For the 992 GT3 RS, the upgrade path is more targeted because Porsche already gives the car a more serious starting point. The question becomes: what does the driver, tire and track surface still need? Intermediate and Advanced are not “lesser” choices; they are the appropriate levels for a car that already begins with more factory hardware. MCS 3-Way belongs in the conversation when the car needs damper control that can keep up with RS-level load.

991 and 992 GT3 Cup cars

Cup cars solve a different problem. They are not looking for a street-car suspension upgrade, and they are not trying to become more “sporty.” They need race-car control: repeatable damping, curb behavior, compliance where it helps the tire and enough adjustment to tune the car for driver, track and class rules.

The Cup MCS package is built around that reality. It gives the car motorsport-grade 3-Way damper control while working with the existing Cup platform. The setup conversation should be based on tire, track surface, driver feedback, ride height, class limits and data, not on a generic street-car upgrade formula.

Dundon Cup suspension arms support the same race-car logic. The 991 GT3 Cup rear lower tension arms are serviceable replacements for the Cup platform, using PTFE monoballs with hardened stainless races, snap-ring retention for bearing service and fitment for the OEM brackets, ducts, clamps and accessories. The 991 Cup / 981/718 Clubsport front lower control arm assemblies add the same serviceable-bearing approach for race cars, with +3 mm and +15 mm length options. These Cup and Clubsport arms are race-car parts and are not intended for street GT3, GT3 RS or other street Porsche applications.

For Cup cars, the value is consistency lap after lap. The car needs to take curbs, recover cleanly, keep the tire working and give the driver a platform that responds predictably to setup changes.

Cup car owners should not think about this like a street-car coilover upgrade. The car already has a race purpose. The improvement is in damper quality, compliance over curbing, repeatable adjustment and how quickly the setup can be tuned around a specific track or driver feedback.

For a Cup car, the right question is not whether the car will be comfortable. The right question is whether the driver can place it the same way lap after lap. A Dundon-spec MCS 3-Way package gives the car the adjustment depth to manage curbs, transitions, braking support and tire contact in a race environment. That is why the Cup package is a race-control tool, not a lifestyle upgrade.

The parts are sold separately — the package is the recipe

One important point: Dundon suspension packages are curated systems, not locked bundles. The individual parts inside the packages are also available separately. That matters because not every Porsche starts from the same place.

Some owners already have adjustable links. Some need only front alignment correction. Some are replacing worn factory hardware. Some are building in phases. Others want the complete package because they do not want to guess.

The package exists to answer the practical question: what does this chassis actually need for this use case?

• Start with the chassis and the factory limitation.
• Match the package level to how the car is used.
• Add alignment range before chasing spring rate.
• Remove rubber compliance where it actually matters.
• Choose Dundon-spec MCS 3-Way as the main damper path when motion control, refinement and track performance matter.
• Avoid selling parts the car does not need.

Recommended combinations

The right package is not always the most expensive package. It is the package that matches the car, the tires, the driver and the way the Porsche is actually used. The Dundon approach is to provide the parts, setup sheet and chassis-specific recipe so the alignment and damper starting point are not guessed.

FAQ

What is the difference between a Suspension Setup Package and an MCS Suspension Package?

A Suspension Setup or Track Day package changes geometry and connection. It gives the car more alignment range, better camber/caster/toe control and less rubber compliance. Dundon provides the parts and the setup sheet, so the car is not being aligned from guesswork. An MCS package changes damping and spring control. It changes how the car moves under braking, over curbs, through transitions and across different road or track surfaces.

Are the parts in the packages available separately?

Yes. The packages are curated recipes. Individual arms, links, shims, bearings, sway bar end links, MCS packages and related components can be purchased separately when a build only needs part of the system.

Is Basic enough?

Sometimes. Basic is the correct starting point when the car needs its first serious alignment correction. But if the car runs sticky tires, sees frequent track use or already has a driver who knows what they want from the chassis, Advanced or Pro may be the better value.

Is MCS 3-Way too much for a street-driven Porsche?

No. A properly specified Dundon-spec MCS 3-Way setup can add refinement to a street car because it separates impact compliance, platform support and rebound behavior. The car can ride better than stock while gaining the precision needed for spirited driving and track use. The key is the recipe: Dundon provides the parts, setup sheet, baseline guidance and support to teach you what each adjustment does.

Where does MCS 1-Way fit?

MCS 1-Way is the budget-focused version where available on selected 911 applications. It has less capability than the 3-Way package because it does not give the same independent control over high-speed compression, low-speed compression and rebound. It can still be a useful damper upgrade, but Dundon-spec MCS 3-Way is the no-compromise recommendation for owners who want better-than-stock street ride quality, track precision and setup control.

Do Cayman and Boxster cars use MCS 1-Way?

For the Cayman and Boxster applications covered in this guide, the MCS recommendation is 3-Way only. The mid-engine platform responds strongly to the additional control and refinement of a proper 3-Way package.

Why do Carrera and Turbo cars need suspension packages?

Carrera cars usually need more alignment range and connection because they are not factory GT cars. Turbo cars need that too, but with the added problem of power, weight and rear suspension load. That is why Turbo packages place so much emphasis on stability and compliance control.

Why do GT3, GT4, RS and Cup cars need them?

GT3 and GT4 cars need precision, tire use and repeatability. RS cars need support for higher tire and aero loads. Cup cars need damper tuning and race-pace consistency. The more capable the car becomes, the more important it is to keep the tire working correctly.
