And I've been working on a brake retrofit. I did the 13.4" C6 Z51 brakes up front and it made the 11.6" Blazer rotors out back look tiny. So I wanted to engineer an interchangeable rotor combo for drag & street wheels. C6 Z51 rear rotors are 13.0" and I found that C6 Z06 rear rotors are 13.4"-and a visual match to the Z51 fronts. So the graphic designer in me has to make it happen.

The ebrake shoe is the same between Blazer and Vette. Check. Center bore is the same. Check. Offset is way off - but a spacer behind the backing plate will fix that. Rotor thickness is about 0.200" different...but shaving pads will fix that. There is enough difference in radius between the 11.6 and 13.4 to make an extension bracket to hang the Blazer caliper further out on the big rotor. So I made some templates out of plastic at work and got it all figured out. I just need to fab the final ones out of steel.

By using the Blazer caliper and pads (which are bigger) I can swap between street & drag brakes without bleeding the calipers or popping out the axles. Should be a 10min job per side. I like the sound of that. Oh - and I found GG friction rated Blazer pads at Advance so I'm all good to go there. Maybe this car will even stop after the rebirth!
