The Brembo GT big brake kit for BMW Z3 M-Coupe and M-Roadster rear applications swaps the rear brakes to four-piston cast calipers with two-piece 328x28 mm slotted Type1 rotors in black. For 1998–2002 Z3 M Coupe and Roadster models, the kit increases rotor size and caliper clamping to improve stopping consistency and rotor cooling during demanding driving.
