Brake upgrade.
 
Good afternoon, first time poster and new member.

I have a 2002 gmc Sierra 1500 rcsb and have already upgraded to from to the 2007+ front brakes… however I have just aquired myself a set of Brembo 4piston camaro calipers P/N 23399515, I know there is companies that make mounts to put the 6P on these trucks, is there anything to mount the 4P?

I did the upgrade on my 96 silverado using 04 spindles and 2020 calipers and rotors.

I have seen the 2020+ fronts quite common, but the camaro 4 piston fronts are different

I did not know the GMT400 was upgradeable that easily.
WHat else did you have to use to make that line up?
