Compatibility for BIG BRAKE upgrades 04 GTP SC?

**showtastiik** · 04-17-2018

Looking to upgrade my 04 GTP SC Brakes... I hear CTS are similar to GXP and Impala are direct fits but what's this about adapters and fittings. I seen 99 Camaro F Body Brakes and I also wanted to put those on. I realised the difference in bolts, FBody and CTS are 19mm and I think, correct me if I'm wrong, 04 and up are 15mm....

What can I do?

2008- 2010 impala front brackts and calipers work good they r dual piston and bolt right up but u also need the rotors to cuz i think the one off the 04+ are to wide the only thing u have to do is bend the brake line a lil bit so its not hitting the bleederi have them on my 05 gtp I defently feel the difference and I got mine from the junk yard and painted them my self
