Brembo 06-12 325i/328i (Excl. xDrive) Rr GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted TY3L - Yellow

If you're looking to significantly improve your BMW 325i or 328i's stopping power and track performance, this Brembo GT Big Brake Kit is a serious upgrade for the rear axle. Designed for the 2006-2012 models (excluding xDrive), this kit replaces your stock rear braking components with a robust, high-performance system engineered to handle demanding driving conditions. You'll notice a substantial difference in braking feel and fade resistance, especially during spirited driving or track use.

This kit features a 4-piston cast aluminum caliper, which offers increased clamping force over the factory caliper. The caliper is paired with a 345x28mm two-piece rotor assembly. The rotors are slotted, a design that helps to vent gases and dust away from the pad surface, maintaining consistent friction and reducing the chance of glazing. The two-piece rotor construction allows for better heat dissipation and can make replacement easier down the line. Brembo calipers are known for their solid construction and reliable performance, and this GT kit is built to match that reputation. The yellow finish on the calipers adds a distinctive visual touch to your vehicle's setup.

When installing a big brake kit, it's important to consider that the increased braking force at the rear might require adjustments to your vehicle's brake bias for optimal performance. This kit is designed as a direct replacement for the rear axle, but it's always recommended to consult the manufacturer's installation guide for specific details and any additional hardware that might be needed for a complete setup. Proper bedding-in of the new pads and rotors is also crucial to achieve their full performance potential.
