The Brembo GT big brake kit for 2006–2008 BMW Z4 M Coupe and Roadster enhances the rear brakes with four‑piston cast calipers and two‑piece 345×28 mm rotors, slotted Type 3 and finished in red. Targeted to those Z4 M applications, the slotted two‑piece rotors improve heat control and contribute to steadier pedal feel under repeated heavy braking.
