sevill rear disc conversion how to

[Beyond]

Thanks for the tips on retracting the piston and the parking brake cables.

The 9" setup that I'm building for a street/strip car uses a combination of low buck circle track parts. Lightweight IMCA spun steel hats with Wilwood .81 ultralight rotors and Southwest speed weld on mounts. The hats fit three different bolt circle combos 4.5", 4.75" & 5". If I had to do it over again, I'd probably go with the OEM Trans Am rotors.

I'm probably not saving but about 2-5lbs of rotating weight with the racing rotors. The problem I ran into is the Caddy calipers are made for rotors that are 1" thick, and Wilwood and others don't make 1" thick 8 bolt rotors. I finally had to make me some .200" pad spacers to get these rotors to work. Haven't tested this stuff out yet, I just finished welding the caliper mounts last night. Should know in about a week how it will work.
