I posted a link over on LS1Tech about the CTS-V caliper swap since I know its been sort of a hot topic over there and I guess no one has research and ingenuity skills these days. This whole setup was a shot in the dark but it worked, wasn't too difficult to get it all in place.
Anyways, the link brings them over here where I have a list of parts you will need...and then this guys says this:
I mean come'on at least read my gat damn thread.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..
I need to go back to tuner/autox/grassroots motorsports forums.
