Re: True C5 Rear Disc w/ internal parking brake in the works

Right, just like the McGaughys kit, the rear axle has to be machined down. One member got his done for around 80 bucks for the pair. I am going to search for a machine shop tomarrow (day off) and have them done. Since the axle's register will be machined down to 2.77 (center bore on the rotor is 2.776) the rotor will be perfectly centered.

When I made the pattern to drill my current rotors (13.8 1/2 Dodge 1500), zero problems.. no wired vibrations or anything, rotors centered on the axle register.
The pattern is super easy to lay on the rotor and make your marks. Then simply drill using a drill press. When I go to drill the rotors for test fitting, I will be sure to bring a camera.
