CTS-V rotors drilled to 6x5 bolt pattern?

Hey guys...

I'm looking for big brake ideas for my TB and other than the super expensive SSBC kits I was thinking that if you got a set of CTS-V rotors and re-drilled the bolt pattern to our 6x5 (6x127) pattern that they could possibly work. Does anybody know if this has been tried or not? The rotors are 14" and only cost ~$70 each, so it'd be a very economical solution. Then you would need to make a bracket to space out whatever caliper you chose to run, whether it be the stock ones or possibly CTS-V calipers or a Corvette caliper of some sort (I'm leaning towards C6 Z06 myself).

One thing I'd be concerned about is the parking brake drum in the rear and the hat depth as well

Why?????????????

Switch the front to the larger setup used in the long wheel base trucks and look for performance rotors that fit.

Because the 'bigger' brakes form the EXTs and SSs are only .8" diameter bigger (12.0" on the short, I6 TBs and 12.8" on the EXTs and SSs). The CTS-V rotors are 14.0"

I like to be able to see big brakes behind the wheels, and I love the stopping performance gained by adding large brakes. The stock ones just aren't cutting it for me any more and for the price of upgrading to the 12.8" brakes I could almost put on CTS-V rotors

Google trailblazer z06 brakes... Do some reading. The baer kit is a more reasonable route. The only read difference is less fade for a few thousand dollar investment, no thanks...

Its not a Trailvoy but I installed a set of slotted rotors( 1" larger) , z rated pads on my Avalanche and it made a HUGE improvement! On a light trailvoy I bet .8" would make a very big difference.

These are all good points, but I've read numerous posts from SS owners complaining of more than just brake fade from their stock SS brakes (which are the larger ones). Plus I'm kind of a big brake fanatic and enjoy putting large, performance brakes from one vehicle on another. Not only does it improve the appearance but the added stopping power is an added bonus

I admire the thought, but even when ADM Performance did their BBK using either CTS-V or Vette Z06 rotors it was a few thousand $$. If you want a BBK, expect to drop at least 2k, probably closer to 3k. There are some good kits being made on the tbss owners site.

like i said, do some reading. people on other sites have put their baer kits for sale as they claim it did not improve stopping distance, only noticeable difference was brake fade.

here is a direct quote from another site

Quote:
Any shorter stopping distance/greater stopping power is negligible and should NOT be bought if shorter stopping distances is what one is looking for - simply too much money for negligible performance - from my point of view.

To do just the rotors with stock calipers would cost me ~$300 (rotors are ~$70 each and I could build my own brackets. Machine work to re-drill the rotors would add some cost in there but I can't see that costing too much)

Now on top of that, you can get a full set of C6 Z06 calipers for ~$1350 (not including pads), so for around $1800-2k I could do a full set of these
