I chose to use 15″ wheels and IRS on my car, but I wanted a multi-piston brake setup. Unfortunately, Factory Five does not offer a big brake kit for this combination so I had to get creative. Gordon of Levy Racing set me up with a menagerie of Wilwood parts and custom brackets to make that happen. I began by mating the rotors and hats. These have specific torque, red locktite, and safety wire requirements. The safety wire was a fun process, but difficult on the rear setup given the tight working space.

Because the rear calipers would be using a custom mount, I had to tap some holes.
