Brembo 06-12 325i/328i (Excl. xDrive) Rr GTS BBK 4Pist Cast 345x28 2pc Rotor Slotted Type3-Black HA

Brembo is a name synonymous with high-performance braking systems, trusted by racers and automotive enthusiasts alike for their commitment to stopping power and durability. For your 2006-2012 BMW 325i or 328i (excluding xDrive models), this Rear GTS Big Brake Kit is designed to significantly upgrade your vehicle's braking capabilities. It replaces your factory rear setup with a more robust system engineered for demanding use.

This kit centers around a pair of cast aluminum 4-piston calipers, which offer increased clamping force over stock calipers. These calipers grip 345x28mm two-piece rotors. The rotors are slotted, a design feature that helps to vent gases and heat away from the braking surface, maintaining consistent performance even under heavy braking. The two-piece rotor construction allows for better heat dissipation and can reduce unsprung weight compared to a solid, one-piece rotor. The black caliper finish and Type 3 slotting pattern offer a distinct visual upgrade as well.

When installing a big brake kit like this, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. While this kit is designed as a direct replacement for the rear axle on the specified BMW models, it's always recommended to consult the manufacturer's installation guide for specific fitment and torque specifications. This kit is a substantial upgrade for drivers looking to enhance their BMW's braking performance for track days, spirited driving, or simply for improved confidence on the street.
