...And I bet your thinking "Oh god, not another one of these threads." Oh but it isn't one of those threads. After seeing a thread on here about Z06 brakes, I did a lot of research for months on end and MANY MANY MANY phone calls later, I am able to present you all with results. Here is a link to the how-to and what not for what I did.

Good **** man very nice. What was the total cost.

DrunkieTheBear

Roughly around $600

I might have to do this. where did you get the rotors. Also it should clear the gxp wheels right?

Also what year did you get the calipers from.

Great success!! Does it 'ENDO'? Any solid performance numbers? Rough amount of feet it took off from 60? Repeated hammering. I have never had a problem with mine just curious! Looks very nice.

I doubt you will be able to run GXP wheels, offset is probably to high, I'm running 32mm offset wheels and they clear a concave wheel with about 8mm to spare.

I got my rotors from RockAuto. Centric Part number 12061089

2005 were mine, any year first gen CTS-V should do it.

These puppies grab and can engage ABS pretty easy if you really clamp down on them, and after numerous hits they still hold up fine (I run a nice brake fluid in my system). Also the break pedal feel is actually pretty nice, I have less brake pedal travel than when I ran a 12" Vette brake setup.

wow i cant believe someone actually did it!

Yeah these look real nice!

Finally someone did it! I was working onit to buh ran out of time, do you have part numbers and venders for the bushings and stuff like that?also how big are those rotors?

All those calipers needs now are some GTP or GXP stickers! Lol

I'm wondering how much "better" these are than the GXP PBR setup that comes from the factory. I mean I thought we had almost 13" rotors up front with 2 piston PBR calipers. I'm no genius but I thought the braking on our cars was pretty good to begin with...



Edit: I'm seeing this isn't on a GXP now so it makes more sense lol

Gxp brakes work very well. But adding 1 more inch to the rotor and two more pistons to the caliper would be even better.

I have a set of 05 CTS-V calipers for sale if anyone is interested. PM me.

I have all part numbers in the link. It should be towards the top of the page with what you need, also a link to where you can buy the bushing.

I was thinking that Since I'm a Comp G, they will get some Comp G decals.

I had the C6Z51 Calipers before this setup and they were stopping my car about the same as my stock brakes maybe a little better, but these brakes actually give me less brake pedal travel (some of it is to do with the SS Lines) and clamp down hard. The added 1.3" and 2 more pistons will make a difference.

I plan to update that thread on GPF.net periodically, Wednesday I will post more pictures of how the Brake line is setup and couple other things, since I suck at pictures and some of them are blurry.

And as an added note, you could change out the CTS-V's for Z06's, but I'd put money that you need to have 19" wheels since I do believe they are a much larger caliper, but I'm not sure. CTS-V's are identical in bolt up to the G8 GXP/'10+ Camaro calipers, which are pretty much the same calipers actually, just different part and pad numbers, but use the same rotor size. Lastly Evo 8 & 9s Ran the exact same calipers as the CTS-V's so you could look for them as well.

i got an 06 impala and im 99 percent sure that we have a 14mm bolt instead than the 12 mm on the older 12mm bolt so this might not be bolt up.at least without swapping spindles..

DrunkieTheBear

That is what the sleeve bushings are for.

You have the same spindle that every w-body from 97-present has.

Just an FYI you can get the same rotors at autozone for $23 less for each one

I tried calling tha local autozones and the didnt even list it.. :/
And sorry I just saw that,and for some reason I thought the 06 and up had a diffrent spindle and used diffrent bolts but again you snapped big time!
