This is our front big brake kit, it uses a Brembo 6 piston caliper and a 14.6" 2 piece rotor. The 2 piece rotor has a CNC aluminum top hat to adapt the ATS-V rotor ring onto your ATS. The stock ATS Brembo front piston area is 5.81 square inches, and our 6 piston Brembo is 8.61", thus a massive improvement over stock.

You will need to also run our Goodridge stainless brake lines. 

Includes:

• (2) Calipers
• (2) 2 piece rotors
• (4) Brake Pads

 Won't fit 17" wheels.
