With 5-lug and centerlock options of our Forged VS-5RS and 5-lug options with the Forged EC-7RS and Flow Formed SM-10. We have fitments ranging from Performance Street and Track which can match OE widths or go a bit wider to Hardcore Track fitments that get you wider than GT3 Cup car wheel widths to best fit your needs.

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. Our 18" wheels clear the optional factory PCCB.

Our most popular fitments for the 997 GT3 with options for OEM tires or a bit wider to aid performance as well as wider wheels that can be a direct fit. This is the section for those of you who drive on the street and at the track. Who want a bit more performance than the car came with, or want to change up the look of their GT3.

These Hardcore track fitments are design for the GT3 that sees more track time than anything else. Something that sees the open road on the trailer heading to next track day. These fitments often require some modifications be it small like camber plates all the way to cup fenders. If you are looking for all out pace, you have come to the right place.
