Brake Clearance Information

The factory 6 piston 408mm steel and 410mm PCCBs require 20" wheels for proper clearance. Read our article for more info.

19" Wheels can be run on this chassis when factory front brakes are replaced with aftermarket kits such as those from AP Racing Essex.

Rear Axle Steering (RAS) Clearance

All 19" & 20" APEX wheels are optimized to clear rear axle steering.

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 following brakes have been tested and confirmed:

  • Porsche Steel 6 piston 408x34mm f. / 4 piston 380x30mm r. - 20" wheels required
  • Porsche PCCB 6 piston 410x34mm f. / 4 piston 390x30mm r. - 20" wheels required, read our article for more info.
  • AP Racing by Essex CP9661 Front 6 piston 394x34mm - 13.01.10141 - 19" & 20" wheels clear
  • AP Racing by Essex CP9450 Rear 4 piston 380x32mm - 13.01.10143 - 19" & 20" wheels clear
