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.

Performance Street & Track
Wider fitments for enhanced performance
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. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the stock 8.5" front wheels. A wider front wheel and tire combination will increase front end grip and close the stagger from front to rear resulting in sharper turn-in and less understeer. This is one of the easiest and most effective improvements you can make to your Porsche from a handling perspective.

Should I Dial in Negative Camber, and How Much is Right for me?
Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hardcore racer competing for a spot on the podium, negative camber is a vital part of chassis setup that has many benefits. Not only will adding negative camber create more room for wider wheel and tire configurations, it more importantly improves handling, turn-in and tire longevity.
