Wilwood rear calipers offset help

[72Z/28]

Hi Guys

I have Wilwood 4 piston Forged Dynolite calipers and realized they are centered on the brake rotor. Both passenger and driver sides rear calipers are not centered. In fact, both of them are more towards the inboard side as shown in the below pictures.





I thought shims would help to center the calipers but I was wrong as you will notice from the second pic that the outboard side of the caliper is almost rubbing against the rotor.

I need your input guys on how to solve this issue.

Where the caliper bracket is bolted to the backing plate there are spacers. Machine spacers to move caliper outwards.

Looks like that was the wrong kit, if that is a 10/12 bolt there are a few axle offsets.

Donny do you mean I should machine the piece that's sandwitched in between



If that is the wrong kit, what is the right kit for my camaro?

Holy crap! that's a solid spacer. I don't know that I have ever seen that but yeah, that piece needs to be thinner. You may be able to just buy it from Wilwood.

Is it a 10/12 bolt? There are 3 different axle offsets, 2.75, 2.81, and 2.91 Looks like the brake kit you have is for a greater axle offset than you actually have.

It is Strange 9" rear end. I removed the caliper bracket, and that spacer turned out to be out of aluminum. It is 0.487" thick spacer as shown in the below pic




I don't know if Wilwood makes thinner spacer than the one I have
