The Brembo rear big brake kit for BMW M3 (2008–2013) pairs four‑piston billet calipers with 345x28 mm two‑piece slotted rotors in a Type1 nickel finish. Sold as a GTR rear BBK, the kit improves rear brake bite and heat dispersion while remaining serviceable via two‑piece rotor construction. It’s a direct‑fit upgrade for owners seeking improved braking feel and reduced fade during aggressive driving.
