^^ Well do you have disc or drums currently.
A disc swap is straight forward. Take the old ones off, put the new ones on. If you have 16 inch wheels, no wheel change is necessary for Camaro/Impala fronts, GXP rear. The GXP, Corvette, XLR set-up require 17 inch wheels. No matter what, you need a 16 inch spare from a 00-05 Impala
The only issue I had with this swap was the rears had to be tapped into place with a hammer. Just tapped, not wacked in like your beating the shit out of somebody you hate more than anything, or Justin Bieber. Like I said earlier, the backing plate makes it a tight fit and after being on my car since 2011, the backing plate will still go back to it's old ways when I remove the bracket.
The only thing I find a challenge is pushing both pistons in at the same time with my C clamp. It can be done, thanks to a swivel head on the clamp.
I had to put the banjo bolts on the rear upside down to fit. No leaks. Just be sure to use the crush washers you get with the calipers and remove the old ones
