2010 Camaro 14" rotors on a 12-bolt. How?

Thanks,

We don't have anything to do what you describe, and as I'm sure you either know or suspect, there's more to it than just the parking brake. The main issue you're going to have pairing the 2010+ Camaro SS rotors with the C5(Z06) rear calipers isn't the parking brake diameter, but rather the rotor thickness. The SS rotor is 28mm thick whereas the caliper is designed for a 26mm thick friction surface. While 2mm [.08"] may not sound like much, it's enough IMO to abort the plan before it even gets off the ground. Additionally, the SS rotors are what would be considered a wide annulus disc, intended to be used with a pad with a relatively large radial height (like the Brembo calipers use). The C5 rear calipers use a D732 spec pad which are designed to be used with a much narrower annulus rotor, so even if you were to machine down the thickness of the SS rotors, you'd still have a lot of under-utilized rotor mass equating to what is essentially dead weight of the rotation and unsprung variety, the worst kind.

Tobin,
I was afraid that was the case. So now, I guess I need some guidance on what to do. With the calipers I have, what size rotor, what kit that you sell? go ahead and spend my money for me.... Am I looking more toward a 330mm rotor? Is that in the LS rear brake category? Or are they smaller?
Thanks for your help.

Tobin,
From what I can see on your site, I think I may be interested in this kit from you.

GM 10/12-BOLT, ø330mm C6 Z51, PARKING BRAKE

Just wondering if the calipers I have will work..

Thanks,

If your caliper assemblies are complete, then you could use them with the 330mm [13.0"] C6 Z51 setup, however you would need the C6 Z51 pad abutment brackets (PABs) to properly position the calipers with respect to the larger diameter rotors. The only setup that will work straight up with the C5(Z06) caliper assemblies will be the 305mm [12.0"] kits they were originally supplied with.

Tobin. Thanks for the info. Can you tell me the dimensions of the hole spacing from the mount to the caliper bolt? Trying to make sure of what I actually have.

128mm [5.039"] is the center to center dimension for the caliper mounts.

Tobin,
Thanks for the info. I will measure when I get home. I found a picture today of them side by side. That will help also.
