Brembo 12-15 335i xDrive Exc MSport Brakes Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot Type1-Yellow

If you're looking to significantly improve the braking performance of your 2012-2015 BMW 335i xDrive, especially if you've found the stock setup lacking during spirited driving or track days, this Brembo Rear GT Big Brake Kit is a serious consideration. This kit replaces your factory rear brakes with a much more robust system designed to handle higher thermal loads and provide more consistent stopping power. It's built for drivers who push their cars and demand more from their braking system.

At the heart of this kit are the Brembo 4-piston calipers, cast from high-strength aluminum for a good balance of rigidity and light weight. These calipers house larger brake pads, which increase the pad surface area contacting the rotor. Paired with the 345x28mm two-piece rotors, which feature a slotted design to help vent gases and dust, you get a system that can dissipate heat more effectively. The two-piece rotor construction also helps reduce unsprung weight and allows for better thermal management compared to a single-piece rotor. The Type 1 slotting pattern is chosen for its balance of performance and noise reduction.

This kit is specifically designed for the 335i xDrive models from 2012 to 2015, excluding those equipped with the M Sport package, which often have different factory brake configurations. Installation will involve replacing your existing rear calipers and rotors, and it's recommended to have a qualified mechanic perform the work to ensure proper setup and bleeding of the brake system. While this kit focuses on the rear, it's often part of a larger braking upgrade strategy. Ensure you consult the included instructions for any specific hardware or setup requirements.
