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.

Our most popular fitments available for the 991 Turbo S and Turbo with both 5-lug and centerlock options available. A great way to both reduce unsprung weight, increase wheel widths, and in certain configurations increase tire width as well. Get the most out of your turbo with a set of lightweight forged wheels!
