Well you have come to the right place as this Porsche 911 991 Turbo Wheel & Tire Fitment Guide has the wheel and tire information you need to select the right specifications for your next set of wheels. Unlock the full potential of your 991 Turbo with a set of our Forged VS-5RS wheels, a great performance option to decrease both unsprung and rotational mass while maximizing wheel width.

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 20" APEX wheels are optimized to clear rear axle steering.
