Brembo 08-13 M3 Rear GTR BBK 4 Piston Billet380x28 2pc Rotor Drilled- Nickel Plated - 2P1.9013AR - Armageddon Turbo & Performance

The GT-R system has been designed for the driver who demands exceptional performance on the street and on the track. It includes 4 or 6-piston monobloc calipers, two-piece floating brake rotors, a selection of friction materials and all the necessary hardware to insure seamless installation. The GT-R calipers machined entirely from billet provide both the benefits and look of a racing brake system: more stiffness, lighter weight (GT-R calipers achieve a weight reduction up to 10 percent compared to casted versions) and more thermo-mechanical resistance, critical in high-performance applications. The two-piece floating rotors reduce unsprung weight and dissipate heat faster.
