Brembo 08-13 135i Rear GTR BBK 4 Piston Billet345x28 2pc Rotor Drilled- Nickel Plated

Brembo is well-known for its high-performance braking systems, and this GTR Big Brake Kit (BBK) for the rear of your 2008-2013 BMW 135i is a prime example of their expertise. If you're looking to significantly upgrade your car's stopping capability, especially for track use or spirited driving, this kit is engineered to provide that enhanced performance. It replaces your factory rear brakes with a robust, multi-piston setup designed for serious braking demands.

This kit includes a pair of billet aluminum, 4-piston GTR calipers, which offer a strong and lightweight foundation for superior braking force. The calipers are paired with 345x28mm two-piece rotors. The two-piece design allows for better thermal management and reduces unsprung weight compared to a single-piece rotor. These rotors are drilled for improved heat dissipation and feature a nickel-plated finish to help resist corrosion and maintain a clean appearance. The combination of these components works together to increase braking power, improve fade resistance, and offer a more consistent pedal feel under heavy use.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's installation instructions carefully. This kit is designed as a direct replacement for the rear braking system on the specified 135i models, but it's always a good idea to confirm compatibility with your specific vehicle setup. The improved braking performance can make a notable difference in both track performance and everyday driving confidence.
