Porsche 911 996 GT3 Wheel & Tire Fitment Guide

The most sought after of the 996 Generation, the 1999-2005 996 GT3 to some, is the last great drivers car from Porsche without the use of some modern drivers assistance systems we get today. Despite having a great wheel setup from the factory, we can still increase performance with a lightweight set of wheels and allow you to change up the look of your GT3 at the same time. This reduced rotational and unsprung weight will have a noticeable positive impact on performance. Unlock the full potential of your new Porsche with options like our Flow Formed SM-10 as well as Forged options in the EC-7RS, ML-10RT, and VS-5RS.

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 are ideal for enthusiasts looking for a more dramatic improvement in performance and they are typically paired with performance oriented summer tires or track oriented r-compounds. Wheel widths mirror the factory 996.2 GT3 specs and do not typically require modifications to the factory suspension or alignment.
