Okay So I bought a LT1 rear off a buddy mainly for the PBR brakes. When i adapted them onto my stock 10 bolt (orig drum) It appeared I woulda needed a 1/8 spacer between the rotor hat and axle. Figuring this was normal due to the drum rear.

Well I ended up finding a Mint 3.23 Tosen LS1 rear with backing plates for an awesome price and bought it. So I installed the LT1 PBR's on it since I had the calipers/rotors. I seem to have the same issue.

The inside of the rotor touches the caliper bracket. It looks liek I could use around 1/8" of a spacer to center the rotor on the bracket.

Has anyone had this issue? No huge rush since I have the car apart for the winter for many suspension mods. I plan on making a summit order this coming week anyways.

I bought an S60 rear end with LT1 brackets. When I put my stock 1LE brakes on it, I needed about 1/8" shims to center mine. This happened on BOTH my cars. I've never gotten to the bottom of it, but it works fine with the shims.

 

I ran into the same problem back in 2002 when I did my rear swap.

LT1 axles are LONGER than LS1 axles.
