Brembo 99-05 330i (Excl. xDrive) Rr GT BBK 4 Pist Cast 2pc 345x28 2pc Rotor Slotted Type3-Black

Brembo is well-known for their high-performance braking systems, often found on exotic and race cars. This GT Big Brake Kit (BBK) for the rear of your 1999-2005 BMW 330i (excluding xDrive models) is a significant upgrade designed to enhance your vehicle's stopping capability. It replaces your factory rear brakes with a more robust setup, featuring a 4-piston caliper and a larger 345x28mm two-piece rotor.

This kit includes cast aluminum 4-piston calipers, which offer increased clamping force over stock calipers. The two-piece rotor design consists of a cast iron friction ring and an aluminum hat, reducing unsprung weight and helping to dissipate heat more effectively. The rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface, maintaining consistent braking performance, especially during repeated hard stops. The calipers come in a black finish, adding a distinct look to your vehicle's rear wheels.

This kit is designed as a direct replacement for the factory rear brake system, though it's always recommended to consult the manufacturer's installation guide for specific details. The larger rotor and caliper combination will provide a noticeable improvement in braking feel and fade resistance, making it a solid choice for drivers looking to enhance their 330i's performance braking. Ensure your wheels have enough clearance for the larger caliper and rotor assembly.
