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.

* The factory 6 piston 410mm PCCBs require 20" wheels for proper clearance. Read our article for more info.

Rear Axle Steering (RAS) Clearance

All 19" and 20" APEX wheels are optimized to clear rear axle steering (images at bottom of guide).

Our most popular fitments for the 991 Carrera GTS, suitable for those weekend drives or occasional track day. A great way to reduce unsprung mass, increase wheel and tire width. These are generally bolt on solutions but some tire configurations could require light suspension or alignment modifications.
