The Brembo rear big brake kit for BMW M3 (2008–2013) includes four‑piston billet calipers and 345x28 mm two‑piece slotted rotors in a nickel finish, identified as a Type3 slotted rotor. Packaged as a GTR rear BBK, the kit improves pad bite and rotor cooling versus stock rear hardware. It’s a direct replacement aimed at owners seeking enhanced braking control and reduced fade in spirited driving.
