A bit of history. The Bosch 82mm Throttle body is the largest Bosch makes and was used as far back as the 996 GT3 which made 380hp. The Air filter box used on the 991.2 GT3 and the 991.2 GT3RS originally showed up on the 2013 991 Carrera S which makes 350hp. Your 991.2 GT3 is rated at 500hp, so you can see just from these numbers that the intake side of things is a constriction.  \u003c\/p\u003e\n\u003cp\u003eIn our testing we found the the stock airbox to be about a 0.2-0.3psi pressure loss and the 82mm throttle body to be about 0.3-0.4psi of pressure loss. Naturally aspirated engines make power from the force of the atmosphere pushing air into the engine, so every 0.1 psi helps! Our combo of 93mm Throttle Body and Dual Cone Airbox reduces the losses to under 0.1psi.\u003c\/p\u003e\n\u003cp\u003eWe tried both our airbox and the 991.2 GT3 Touring Airbox and found our airbox to only be slightly better but the Touring box is less expensive, so we decided to include the Touring airbox for the single opening decklid cars.

We have tailored three spring packages depending on your use case. Street Springs give you supreme ride quality and comfort while raising the bar of the platform. Track Springs for drivers looking to improve their track performance, but also maintain a street-friendly attitude. Our Race Spring option gives the car more support needed when using stickier tires (like a Hoosier or Racing Slick) and enhanced aerodynamics.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eKit includes:\u003c\/p\u003e\n\u003cp\u003eDundon-spec MCS 3-Way Remote Damper System\u003cbr\u003eInstall Hardware Kit\u003c\/p\u003e\n\u003cp\u003eFront Camber Plates\u003cbr\u003eRear Camber Plates\u003c\/p\u003e\n\u003cp\u003eCurated Spring package (Track or Race)\u003cbr\u003eReservoir Mounting Kits\u003c\/p\u003e\n\u003cp\u003eKW PASM Delete Module\u003c\/p\u003e\n\u003cp\u003ePre-Assembled for easy setup and install\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eTalk to us about adding a \u003ca href=\"https:\/\/www.dundonmotorsports.com\/products\/dundon-setup-package-991-gt3?_pos=3\u0026amp;_sid=0551b296a\u0026amp;_ss=r\"\u003eDundon Track Day Setup package\u003c\/a\u003e to complete your suspension overhaul!\u003c\/p\u003e","brand":"Dundon Motorsports","offers":[{"title":"3-Way \/ Track Spring Rates","offer_id":39635046105263,"sku":"400-30021","price":12195.0,"currency_code":"USD","in_stock":true},{"title":"3-Way \/ Race Spring Rates","offer_id":39635046170799,"sku":"400-30022","price":12195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0075\/5046\/8132\/files\/mcs-3-way-suspension-package-for-991-gt3-without-front-axle-lift-2278678.jpg?v=1772089936"},{"product_id":"copy-of-mcs-2-way-3-way-damper-kit-for-991-gt3-with-front-axle-lift","title":"MCS 3-Way Suspension Package for 991.1 \u0026 991.2 GT3 with front axle lift","description":"\u003cp\u003eFor a long time you had to sacrifice your street drivability if you wanted to upgrade to a motorsports damper.
