Z28 brakes

Who else is thinking it? The caliper looks very close to the current ZL1/CTSV but the rotors are larger. Did they stuff a larger rotor in the same caliper so we can just swap the ceramics over? Or is the offset and spacing from center different? It's a .95" taller rotor than a ZL1. I don't have time to pull my wheels to see if they'd fit in the current caliper. And without knowing the offset and dimensions it would only be conjecture anyways.

Probably going to be guessing for another year but I want those friggin rotors.

This was my first thought after seeing the Z/28. It might be a long while before we find out...

Yup. And if I'm going to spend 1300 per rotor I'd rather have these than Racing Brakes. Lasts longer, a ton less weight, and over 1.5g's in braking? Sign me up.

It will be a unique caliper and pad. CCM brakes have different requirements then metal rotors.

Guess I'll be selling my current 6 pistons. Although the pricing will probably be too crazy to justify it.

Try about $2,000 per rotor. And Racing Brake rotors are only $450 each.

MSRP is that for the corvettes but you can get them MUCH cheaper by shopping around. And where are they 450?

edit: I was thinking the pair pricing but said individual pricing. I know the carbons will be more individually.

Ha, just found the rotors for $918 with free shipping for the ZR1 ceramics and it only took 30 seconds with google and some part numbers. People just want to buy everything as a kit at retail to make it "easy" and get bent over. I get enough of that at work, don't need to get bent over in my hobby too.

My best guess is the brakes are ZR1s. The lead engineer on this project is a well respected Pro-Touring car builder and have been installing ZR1 brakes on his personal builds for several years. I suggest you check the bolt pattern and offset for the ZR1. If they match the Camaro....

I'll ask Danny Popp.

Pete,
That was my guess as well and looked yesterday. The front rotors are the same height and width and the bolt pattern is 5x120.65 versus 5x120. The question becomes offset of the aluminum hat and caliper placement which I couldn't find dimensions on. Pads would make sense to carry over.

The rears appear to be a unique size so I'm not sure if anything will carry over. I was expecting parts sharing due to the price of such a low volume part, maybe the rotor size is used on another vehicle that gets the carbon ceramics from brembo...?

Anything you could find out would be awesome. They need to offer conversion kits similar to the ZL1 brakes. Bigger is better on our big boned girls.

I can't find the widths today for some reason, but yesterday they were the same when I found the info.

Z28 front: 394 x 36 mm, 5x120
ZR1 front: 394 x , 5x120.65

Z28 rear: 390 x 32mm
ZR1 rear: 380 x

Any updates on this thread? I would love to have 6 piston rears to match my fronts. Anyway we could use the ZL1 front caliper on the rear?

Would the fact that the SS lug bolts are 14mm vs the 12mm on the Corvette play a role in fitting?

Chevrolet in their infinite stupidity put the parts on restriction because they're a bunch of dickheads.

You don't need 6 pistons in the rear due to natural brake bias of any car. And no it wouldn't work without custom machining/effort.

I'm thinking if we can get some brackets fabricated and use the stock rear ss rotors???
The ctsV front rotors I'm running now are 14.9 so I wonder If the 6 piston calipers can be used with a 14.4 rotor that our rear uses now?

So what's the difference between the Z/28 rear caliper and the ZL1 front caliper that would make it not be able to work? Mounting location, mounting lug size, offset? Sorry if it's a dumb question.

Rotors, calipers, and pads need to be balanced. The Z should also have a unique master or the caliper balance has been maintained by sizing and piston size. Throwing exactly the same caliper/rotor front and rear does not mean you will stop faster and will easily result in an unbalanced braking situation.

Ok thanks, that makes perfect sense. The ZL1 brakes stop great for me now, I was looking for more of a unique look with the rear 6 pistons to go with the front.
