This is our rear big brake kit, it uses a Brembo big 4 piston caliper and a 14.4" rotor. The stock ATS rear caliper piston area is 2.07 square inches, and our rear 4 piston Brembo area is 4.40 square inches! This kit will fit behind the stock 18" wheels, but it wont fit with the stock 17" wheels.
You will want to also run our Goodridge stainless braided brake lines.
CTS note: This kit will fit '14+ CTS, the only extra component that is needed is a pair of 10mm fine threaded Banjo bolts and copper washers, and you will have to trim the outer backing plates for the larger rotor.
