Brembo 08-13 135i (E81/E82/E88) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1- Yellow

If you're looking to significantly improve your 2008-2013 BMW 135i's braking performance, especially for track days or spirited driving, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit replaces your stock rear braking components with a much larger and more robust setup designed to handle higher temperatures and provide more consistent stopping power. The calipers are a substantial 4-piston design, paired with large 345x28mm two-piece rotors that offer more surface area for heat dissipation and friction.

The rotors in this kit are slotted, which helps to keep the pad surface clean and clear of gas and debris, ensuring better contact and more reliable braking, particularly under heavy use. The two-piece rotor construction is notable because it allows the rotor ring to expand and contract more freely with heat, reducing the risk of rotor warping compared to a single-piece design. This also makes replacement of the rotor ring easier and more cost-effective down the line. The cast iron calipers are built to withstand the rigors of performance driving, and the yellow finish adds a distinct visual appeal behind your wheels.

This Brembo GT Big Brake Kit is engineered for a direct fit on the specified BMW 135i models (E81, E82, E88 chassis). While it's a comprehensive kit, always refer to the manufacturer's installation instructions for specific details regarding mounting and any additional hardware that might be recommended for your particular setup. This kit is a substantial investment in your vehicle's performance and safety, offering a significant step up from the factory braking system.
