c5 vette brakes

There are several options for upgrades on that page. You're probably going to need bigger wheels if you're still using your originals.

you'll need a min of 17in rims. it's highly recommended to upgrade the master cylinder, the rear brakes and proportioning valve. one commonly for gotten part is the correct brake hose, check kore3.com

drilled and slotted are a bad idea for anything but racing, where you'd replace them at every use. other than the small gas grooves the usual slots and especially the drill holes are nothing but weak spots where cracks form and the rotor breaks.

hey clutch_grabwell, i like everything in that kit except the rotors. i wanna run slotted and cross drilled rotors. cant i just replace those from the kit with the cross drilled and slotted?

You should contact the vendor. He may be able to substitute rotors for you.

And as a note, you WON'T be able to use them with any form of a 17" American Racing Torque Thrust wheel. At least not with the 13" rotors.
I found this out after buying my 17's and then trying to get my brakes to fit. The wheel hoops weren't big enough to clear the calipers and the spokes in the rim rubbed on the face of the caliper.
My solution for the time being was to use the 12" LS1 rotors which helped the calipers to clear everything.

Good thing i haven't had the cash to buy those? What is there to look at when buying rims to fit? I thought 17's would clear, so should i just aim for a bigger rim like a 18? I am in the process of doing that swap as well.

Well, they didn't have these when I pieced together my kit but you can now download and print the templates for the C5 brakes and test fit them in your wheel or at least determine if the wheel your looking at will work:

The problem with the American Racing 17's is how they design outer hoop. I don't believe I have a picture of it but on the inside of the rim (backside of the spokes) there is a 1/2" lip that ends up making the wheel diameter smaller. This is one of the problems. If that 1/2" lip wasn't there, the calipers would fit.

The other problem specific to the TTII type wheels is how they're spokes are shaped. You can look at my wheel pic here and kind of see how the curve back towards the caliper:



This picture is with the 12" LS1 rotors and the caliper moved closer to the center of the wheel to compensate. So essentially in this picture, they fit properly. However, if you can imagine with the original 13" rotor, the caliper gets moved out further (radially) and puts it right where the spokes curve sharply back toards the wheel.

The only other way to have solved this issue would have been to use a set of billet wheel spacers and then order the wheels with a backspacing that would then work with the spacers. Not exactly the route I would want to take personally.

As far as whether or not an 18" wheel would fit, you'd have to find out how American Racing makes their wheels.

I know down the road I plan on upgrading to a larger rim and tire so that I can run a larger brake setup than the C5 setup.

Well i have the non zo6 C6 calipers with the regular C5 Calipers abutment brackets and the rotor size i believe 12.8. Will this cause a interference problem? There is two different abutment brackets one for 12.8 rotors and one for 13.4 rotors right? I will check out that link so i can make sure what fits though..
