Chris,
Where are those backing plates from?

They are Wilwood parts that I bought from Summit. (The replacements, anyways.) I highly suspect that Red loctite wasn't used when this was re-assembled with those washers.

I spent some time of the phone with Wilwood today - they supply thicker brackets that should be able to fix this for me - We'll give 'em a shot.

There are spacers to go behind the backing plate to help dial in the spacing behind the backing plate and the housing if you need to go in that direction to maybe eliminate the washers. Again if that's the direction you need to go.

Yeah - Wilwood makes different thicknesses of the spacer between the backing plate and the bracket that the caliper attaches to. I ordered the two biggest sizes and will see if that works.

Gotcha but I was talking about between backing plate and rear end housing.

I see what you mean - that’ll move things in the wrong direction, though. Caliper mounting plate goes on the rear of the brake backing plate. When I put the rotor on, it contacts the caliper mounting bracket. That’s the bracket that I need to move inboard a bit.

I see what you are talking about. On my car I has already converted my rear brakes to S10. Then I converted those to Wilwood. Those aluminum brackets you are using wouldn't work for me because the two bolt holes where the bracket mounts to the backing plate are a different dimension. What I did was design a similar bracket to yours but used 3/8 steel and had them water jetted. So far so good.

Okay, I went and bought a propane torch in preparation to disassemble the as-delivered “assembled at the factory with Red Loctite” backing plates. I figured I first try it by hand and ... they came right apart.

The thicker backing plate looks like it works well with no rotor contact. I’ll mock up the caliper, take it all apart and torque/apply loctite, and we’ll be ready to go.
