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.

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 and they are typically paired with performance oriented summer tires or track oriented r-compounds. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the more "generic" 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.

We've optimized the offset of our 9" front wheels to to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber to fit properly. See fitment notes under each tire configuration below to see if modifications are required. If you plan to track your car, we highly recommended dialing in negative camber regardless of whether your wheel/tire fitment requires it for fender clearance. Negative camber is vital for extracting the most performance and longevity out of your tires, and without the proper amount the outer shoulders of your tires will wear out prematurely and running tire costs will dramatically increase.

Hardcore Track & Race

All-out performance for fastest lap times

These wheel and tire configurations are best suited for hardcore track junkies and club racers competing for a spot on the podium.  Everything from Extreme Summer tires to full Racing Slicks are commonly used depending on your experience behind the wheel, class rules, etc. Most notably, these fitments incorporate wider 9” front wheels (or 10" wide if you are real hardcore) 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.

We've optimized the offset of our 9" front wheels to to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber to fit properly.

Should I Dial in Negative Camber, and How Much is Right for me? 

987.jpeg

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. Learn more in our blog article, The Positives of Negative Camber.
