991.2 GT3 RS «Lab Rat» Performance Package

This is the complete performance system for the Porsche 991 GT3 RS. Every component is engineered, tested, and track-validated to work as a cohesive unit — not just standalone mods.

We start by unlocking real power with our D3 Street Power Package, which includes long-tube headers, a tuned intake, and our signature Lifetime Muffler. The result? +52 lb-ft of torque and +45 whp you can feel in every gear.

Then we add the Valkyrie Complete Air Package — a full carbon aero system including a swan neck wing, dual dive planes, and a front splitter. This isn't just for looks — it's tested to improve front and rear downforce, reduce drag, and increase stability at speed.

Handling is completely redefined with the Dundon Track Day Setup Package: titanium tie rods, caster and camber adjustability, adjustable end links, shims, and arms — plus MCS 3-Way Dampers that retain front axle lift and allow high- and low-speed compression plus rebound tuning. It's precision race-car control with street-level usability.

We complete the system with Forgeline GS1R lightweight forged wheels, reducing unsprung mass for better acceleration, braking, and chassis feel, and Performance Friction braking components — the same used in pro-level racing — for serious stopping power with fade-free consistency.

Everything in this package is backed by engineering, data, and real-world track time. This isn't a parts bin build — it's a proven setup, developed through the same 3D scanning and modeling we use for our championship-winning clients.

For Whom This Product?

The 991 GT3 RS LabRat Package is built for Porsche enthusiasts who drive hard and demand results.

It's for the owner who wants a car that feels as fast as it looks, and delivers real lap time improvements — not just dyno numbers or carbon trim.

If you track your RS regularly, or you're looking to run up front in PCA TT, SCCA, or local club events, this is the exact setup we recommend. You'll experience balanced grip, stable aero, explosive torque, and confidence-inspiring braking — every single time you drive.

You're not chasing trends — you're chasing precision. You're looking for a system, not a guess. You want the car to do what you tell it to, and reward you for pushing harder. That's what this package is about.

And let's be clear — once installed and dialed, this LabRat-built 991 GT3 RS drives like a 992 GT3 RS, with better sound, sharper feel, and custom-tailored behavior that fits your driving style.

If that's what you're after — this is your build.
