So here's some background.
I've been thinking of some fixed calipers from a production car (for ease of parts) thatll clear a 15 inch wheel. The only ones that I could think of are from a c3 corvette. Awesome enough at my job they have a few pairs of calipers. Now my question is the rotors, the factory c3 vette rotors have too much offset. So I was looking at a pair of ls1 rotors which are the same diameter but. 04 mm thicker. Will that be a problem for the clearance between the pads and the rotor? I test fitted the pads rotor and caliper, and they physically fit onto each other, is that good enough?

 

C2/3 calipers are junk with the lip seal and loose tolerance spring loaded pistons. The wilwood replacements are pretty damn good but why use that if you can simply get any other decent caliper. Stay away from leaky c2/3 vette calipers

 

Okay so what other fixed caliper setup will clear a 15 inch wheel

 

So a little more research has been done, the reman calipers from autozone have updated seals and updated stainless steel pistons, so they should be better than regular c3 calipers. I retest this then today while I was there again, they physically fit together and even with the cellophane on the rotors the caliper spun relatively freely? I think it should be fine??

 

They are also cast iron and get heat soaked very quickly - unlike modern aluminum calipers.

I would stay away.
