The Brembo Rear GT big brake kit for BMW M3 (2015–2018) configured for CC brake–equipped cars combines a four-piston cast caliper with a 380×28 mm two-piece drilled rotor in black. It provides a direct-fit rear upgrade that improves thermal control and pad bite consistency; the two-piece drilled rotor helps vent heat and resist fade while maintaining factory-style mounting.
