The Brembo rear GT big brake kit for 2023+ Z (RZ34) applications pairs four-piston cast calipers with 380×28 mm two-piece rotors featuring Type‑3 slots and a silver finish. This rear-specific upgrade matches cast four‑piston calipers to slotted two‑piece 380x28 mm rotors to promote stable pad engagement and debris evacuation under heavy braking, while the silver finish keeps a refined appearance.
