The entire premise of the ZR-1 was to be able to bring in a dual pattern camshaft for vacuum and emissions reasons. As you know, it is very complicated to bring in the secondary ports. The L88's had little vacuum, and Chevrolet did NOT want the public driving that car because the brake booster would not work in traffic, and the car could not stop or go into a turn at 160mph without a booster.
The LT-5 was a modern solution to this dilemma. I specialize in HYDROBOOST power brake conversions, which run off of the p/s pump, and need NO vacuum. The stopping power is incredible, as 2000psi is available to the calipers, even at idle pump speed. I have done these before on Big Block C-4 conversions, but will be prototyping a Hydroboost on my own car soon. I will have the hoses and brackets dialed in for those who want the very finest in brakes. I will use the more common 1" master cyl, eliminating the weak and expensive 13/16' or 7/8' original master cylinders. This will give a much firmer pedal feel. With High pressure, the car stops in nearly half the distance. This has the effect of not heating the rotors, and eliminating the need for giant rotors. |

C6 Z06 brakes are very pricey.... If you go "cheap", they are 2k. C5/C6 brakes are a great value @ under $600. ![]() David |

I just want to get an idea of what I need to buy next month at Carlisle. I plan on spending some serious $$$ on everthing I need ZR1. I want GM bigger brakes on the 92 project car. It would be nice to buy everything I need while I'm there.
I also need a perfect hood and front bumper assembly.

Wilwood 6 piston in the front. I think 4 piston in the rear.

I'm contemplating what to do. I just looked at the C5 Z06 calipers on ebay and the brackets for them. About $600 for that setup. Brembos are intriguing though.

I've been keeping an eye on them because I have a friend with a C6 in the market for them. To the OP, it is the 14" rotor diameter and the fact that your wheels are only 17" in diameter that makes them unlikely to work. Not any kind of spoke to caliper clearance. |

Need different SS lines, rotors, calipers, pads, etc etc etc. Ask Ricky... VERY pricey! C5 / C6 brake upgrade is the best for the $$$$$ and looks great! ![]() |
