Specs: Moser 12-bolt with every option and 3-channel ABS (33 spline HD eaton, 1350 yoke, TA cover, etc)

I need this car running soon - I have a track rental coming up so I need this fixed ASAP

I just got the rear today, painted it, took the driveshaft and and axles to get the u-joint and axle bearings pressed on...came home and got to work.

I got everything in without any issues, U-joint has enough clearance and whatnot.

Got the wheels on, filled the rear w/fluid, and (on jackstands) with the wheels spinning, and heard a slight grinding sound coming from the driver side. Took the wheel off, and the BACK of the brake caliper (towards the housing) is rubbing against the rotor...there is no pad contact, just the rotor rubbing on the steel caliper. It is also very hard for me to turn the axles by hand (even with the brakes off). It seems like it's mainly on the driver side, as that axle was pretty damn hard to get in. I had to tighten the T-bolts and pull the axle into the housing that way.

AFAIK the 1/8" spacers were installed because I don't have any leftover parts..

Please help, I'm very frustrated and stressed

sounds like the caliper bracket or where it mounts is bent to be honest

I haven't installed a 12-bolt yet (just trying to help any way I can), but assuming everything is assembled correctly, can you grind a little material off the caliper? Also, I remember reading that there's a brake caliper weight that needs to be cut down, not sure if this has anything to do with the rubbing you're experiencing.

It happens because Moser uses the wrong dimension for the brake spacing - I went round and round with them on this. Easiest thing for you to do is put a couple of washer shims between the caliper mount and caliper to get you the clears.

I put 1/8" washers behind the rotors, and now everything is perfect. Rear is dead silent...

I tried sorta free revving it within the stall range, and it wouldnt go over 3000 RPMs and was popping and such. At this point I was questioning my presence at the track rental this weekend, but I filled it with gas since I heard my fuel pump getting very loud, and now it's fine

I missed the boat on this one, but good to hear you fixed it. Good luck.

Hopefully you didn't hurt the fuel pump! Bob

It is whining, not sure if it was louder than it used to be since that rear deck panel and rear driver side panel are out, and it was the first time driving it in 2.5 weeks.....but it pulls fine in upper RPM's. I'll put a gauge on it before I spray it.

LOL

You would think they could get some simple **** w/a product that costs so much....oh well. It's set up damn good...can't hear the thing at all so I'm not going to complain.
