Brembo 08-13 135i (E81/E82/E88) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black

This Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW 135i (E81/E82/E88) includes everything you need to significantly upgrade your braking performance. You'll receive a pair of Brembo 4-piston GT calipers, two-piece 345x28mm drilled rotors, caliper mounting brackets, and all necessary hardware for installation. This kit is designed to replace your factory rear brake components with a more robust and capable system, offering a noticeable improvement in stopping power and heat management.

The calipers in this kit are cast from high-strength aluminum and feature a 4-piston design, which allows for more even pressure distribution across the brake pad and rotor surface. This translates to more consistent braking force, especially during repeated hard stops. The rotors are a two-piece design, measuring 345mm in diameter and 28mm thick, with a drilled surface pattern. The drilled holes help to dissipate heat and gasses, preventing brake fade and maintaining optimal performance when you need it most. The black finish on the calipers and the drilled rotors give your vehicle a distinct, performance-oriented look.

Installing a big brake kit like this is a significant upgrade that can transform the feel and capability of your vehicle's braking system. It's particularly beneficial if you frequently drive your 135i hard or track it. While this kit is designed as a direct bolt-on replacement for the rear axle, it's always recommended to consult the manufacturer's installation guide for specific torque values and procedures. Ensure you have the appropriate tools and knowledge for brake system work, or consider professional installation to guarantee optimal performance and safety.
