The Brembo GT big brake kit for BMW 330i (2006, excluding xDrive) rear applications pairs a four‑piston cast caliper with a two‑piece 345x28 slotted Type‑1 rotor in silver. This direct‑fit rear kit increases rotor size and cooling capacity with a two‑piece slotted design and compact four‑piston calipers for improved control over repeated stops.
