1994 Brake Upgrade Question
I am looking to upgrade the brakes on my 1994 ZR-1 and want to know whether this rear brake kit

will work on a 94 Corvette. What changed between 1984-87 and 88-96? This kit is for the early years, and there isn't one available anywhere for the 88-96 model Corvettes.
I am going to use this on the front and want some Wilwoods that match.

Biggest difference in the years is that the 84-7 rear brakes had an internal drum-type parking brake. The rotor "hat" served as the drum. '88 and later C4's used the rear caliper for the parking brake.
So the difference could be in the dimensions (depth) of the rotor hat. Did you contact Wilwood directly to see if they make a rear conversion kit for the later year C4's?

They don't.
For the C4 you have a choice of the complete rear big brakes on the 84-87 or rotors only on the 88-96 years.
Only the older cars have the 'drum in disc' set ups allowing for full four pot and larger rotor options. The later cars; you're stuck with the combo parking brake caliper you have now. There are no tween or conversion kits produced by Wilwood. *Doesn't mean someone hasn't offered something...possibly including Wiwood calipers even, but I've not seen them and they are not produced by Wilwood.

I emailed the guys doing the Street Shop mod mentioned on the ZR-1 Forum and got some pictures of their parts, which look like they have to fit inside that part of the rotor, so I'm not sure how the C5 Rotor would work at all, but supposedly I would by the C5 Caliper and Rotor package and use the parts sold below on my C4. I've been told I will also need longer wheel studs and different caliper bolts and have a source for them, but would the C5 Rotor cause my wheels to offset out further than normal? The street shop mods are currently sold to upgrade from C4 to C5 brakes all around. So I figure the C5 Willwoods would work just fine with this.
Does the C5 use a drum parking brake?
