Well a 1987 Road & Track I have says my '87 should do...
60-0 : 131 feet
80-0 : 230 feet
Take it for whats its worth, its a magazine. Tires are much better now and I have miserable 11.5" rotors.

I never physically measured, but I can make the first turnoff at Raceway Park, not an easy feat at 108-110 mph!
Most cars need to go to the second turnoff at the very least. I usually use the 2nd or 3rd to save the brakes, but as part of a test I was conducting, I tried the first turnoff and no problems.
I wish I could tell you the distances.

Reading a Motor trend mag here from 90. Should be similar results for a 87. 3300lb 6sd coupe with 13" brakes 30-0 28ft, 60-0 112ft, 3284lb auto coupe with 12" brakes 30-0 29ft, 60-0 109ft. zr1 for that year did it 27ft and 109 ft weighing 3481.

Wow: The ZR1 only took 4 ft longer than the shortest I've seen for a Z06. The weight alone would account for that difference. Maybe the C5 brake set-up isn't that much better than a J55 after all. :confused:

Is the brake fade bad?
I'm thinking of retro fitting the 12" setup to the front of my IROC-Z. The 10.5" 1 piston items are, in a word, crap. There is also a lot of fade with them.
I'm thinking that the 12" C4 setup would be a good upgrade that will still allow me to keep the stock 16" wheels. The C5 setup seems to just hit the caliper, and I don't want to spend all that money and have them not fitting or have to grind down the caliper.
Also, was there a 1 piston caliper on early C4s?
