You can get the calipers from Amazon and hot damn are they cheap!

Last time I checked, our OEM calipers (2 piston sliding) were well over $250 each. One side (not sure which one) CTS-V caliper (4 piston fixed) is $101.31 shipped. The other is $126.38 shipped.

ACDelco 172-2287 Caliper Assembly : Amazon.com : Automotive ACDelco 172-2287 Caliper Assembly : Amazon.com : Automotive

ACDelco 172-2288 Caliper Assembly : Amazon.com : Automotive ACDelco 172-2288 Caliper Assembly : Amazon.com : Automotive

Good luck.

EDIT: This site sucks for links. No I did not post four links. *sigh*

Ignore Amazon's image for part number 172-2287. It's the correct part.

I got camaro ss brembos, so all I needed was washers to get the pad spacing right. All I used was a auto zone 6" hard line and union and a zzp extended length gxp braided line. And the two washers mentioned earlier.

it'll work you just need to check your wheel clearence. For the impala you'll probably need some wheel spacers
