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.

These bolt-on wheel fitments are ideal for the 718 owner enjoying their car day-to-day on the street, and they are typically paired with all-season or performance oriented summer tires. These wheel and tire configurations will improve the appearance and performance of the car without requiring modifications to the factory suspension or alignment. Just bolt-on and enjoy!

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 which provide superior tire sidewall support over the more "generic" 8.5" front wheels typically found on a 718. These fitments prioritize performance over ease of installation. Some of the below options may be a direct fit but other require increased camber through camber plates to ensure fender clearance.
