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.

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 (when dialed in through the top hat / camber plate), it more importantly improves handling, turn-in and tire longevity. Learn more in our blog article, The Positives of Negative Camber.
