ATS Brembo 4 Piston Calipers

One of the cheapest and easiest ways to bolt a 4-Piston Big Brake Kit on the W-Body platform is to use Cadillac ATS Brembo Calipers. These calipers can be found on the non-V models of the 2013-2016 Cadilac ATS and the 2014-2016 CTS. 

When these calipers are used in conjunction with 2005-2008 Pontiac Grand Prix GXP rotors, you have an effective 12.7" Big Brake Upgrade with 4 Piston Aluminum Calipers on the cheap. 18" wheels or larger are required.

LS4 King has acquired a larger inventory of used assemblies. These calipers are available for purchase in pairs of left and right.
