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 408mm Steel and 410mm PCCBs require 20" wheels for proper clearance. Read our article for more info.

Rear Toe Link Clearance

APEX 19x11" ET48 rear wheels require the installation of aftermarket motorsport style rear toe links from companies such as Tarett, GMG, SP Motorsports, or BBi to achieve the clearance needed for the reduced wheel diameter. This will also allow you to correct your toe setting when dialing in more negative camber at the rear.
