I also scored a set of wilwood FDL calipers, 88 adapters (very easy to copy), and 13" rotors for the front in the same deal as the control arms.. but I'm not thrilled about the 'race-only' status of these calipers, i.e. no dust seals, rattling, squealing for a part time daily driver.
Before I look at copying the adapters and purchasing nicer wilwood calipers I want to exhaust looking at adapting the C5 brake setup. I have a full set on hand and I've got a working demo of the rear C5 parking brake working on the 88 rear hub with a plexiglass bracket... however, I'm still looking at the oem C5 caliper brackets and how to adapt them to the 88 hub/knuckle. The 88 caliper holes are 3" on center and the C5 brackets are roughly 5.09" on center, however the damn C5 bracket has a cross bar between the mounting holes that prevent a standard offset caliper adapter from being made.

The only way I can see getting these to work with an 88 knuckle is to cut the cross bar between the mounting holes, offset/clock the bracket to straddle the 88 mounting holes like most other adapter setups, and then tying it all together with a custom bracket. So effectively, the C5 mounting holes would be tied together just not in OEM form.
Safe? Stupid? Not worth the risk?
Thoughts?
