Brainstorming future brake upgrade - Page 2 - ZR-1 Net Registry Forums

JimZRyd · 04-27-2014

My original post was just asking for some feed back on a few replacement rotors...not a "who's got the biggest" pressure generating system. My Z's not a track car. If it was then I'd be interested in Learning more about Bobs system. So what about rotors guys? Anybody got anything else to add?

What USA said.

Be cautious of brake upgrades. The stock J55 setup is a pretty good compromise between stopping and living with the system, although I would prefer a larger master cylinder bore and more rear bias in our ZR-1s. It's pretty easy to wind up with expensive to maintain components that are waaaay too noisy and dusty for street use. A lot of the "upgrade" pads are not designed to work when cold - which is how most street brakes spend their time.

I have found that the Carbotech AX6 is a great "cold" brake pad but even that needs me to drag the brake pedal a bit before first real need. It is wildly dusty and a little bit noisy, but the dust is very benign - doesn't eat your paint (like many do).

And when it comes to rotors, the drilled ones just give you more places for cracks to start. If you must have holes look for cast-in ones, which I don't think you'll actually find.

HTH,

How much and what color are they?

Unless you are racing or maybe you need to have calipers which are bigger and more colorful to give your car a badder look, the stock brakes on a ZR-1 are pretty darn good.

If you need an upgrade but are looking for a bolt-on, high-bang-for-the-buck modification, I'd try a slightly more aggressive brake pad, one of those aftermarket front air dams with brake ducts along with a fluid flush.

I just dressed up my stock calipers until I find a set of 96 GS calipers
