Porsche 911 996 GT2 Wheel & Tire Fitment Guide

Brake Clearance Information

In the engineering phase of wheel development we 3D scan factory brakes and review 2D aftermarket brake templates in order to optimize our barrel profiles and spoke curvatures. As a result, our wheels offer massive brake clearance so you can run the smallest possible wheel diameter.

Whether you enjoy spirited street driving or you are a weekend track warrior chasing lap times, these wheel & tire configurations improve the appearance and performance of the car without requiring modifications to the factory suspension or alignment. The 8.5" front wheels and 12" rear wheels mirror the factory GT2 wheel widths.

These fitments are best suited for weekend track warriors and competitive club racers looking to maximize grip and overall performance. They incorporate wider 9” front wheels which provide superior tire sidewall support over the stock 8.5" front wheels. A wider front wheel and tire combination will increase front end grip and close the stagger from front to rear resulting in sharper turn-in and less understeer. This is one of the easiest and most effective improvements you can make to your Porsche from a handling perspective. 

We've optimized the offset of our 9" front wheels to to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber to fit properly. See fitment notes under each tire configuration below to see if modifications are required. If you plan to track your car, we highly recommended dialing in negative camber regardless of whether your wheel/tire fitment requires it for fender clearance. Negative camber is vital for extracting the most performance and longevity out of your tires, and without the proper amount the outer shoulders of your tires will wear out prematurely and running tire costs will dramatically increase.
