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

If you're looking to significantly improve your 2012-2015 BMW 335i or 335i xDrive M Sport's braking performance, especially for spirited driving or track use, this Brembo rear GT Big Brake Kit is a serious upgrade. This kit replaces your factory rear brakes with a much more robust setup designed to handle higher temperatures and provide more consistent stopping power. The heart of this kit is the 4-piston caliper, which offers more clamping force than the stock unit, working in tandem with the large 345x28mm two-piece rotors.

The calipers themselves are cast from high-strength aluminum for a good balance of durability and weight savings, and they're finished in a sleek black to complement the look of your M Sport model. The two-piece rotor design is notable because it allows the rotor ring to expand and contract freely with heat, which helps prevent warping and cracking over time. These rotors also feature Type 1 slotting, which helps to sweep away dust and gas buildup from the pad surface, maintaining optimal friction and reducing noise. This combination of advanced caliper design and high-performance rotors means you'll experience improved pedal feel and significantly reduced stopping distances, even under demanding conditions.

This kit is designed as a complete rear brake solution, and it includes everything you need to get these powerful brakes installed. You'll find the Brembo 4-piston calipers, the 345x28mm two-piece slotted rotors, and all the necessary mounting hardware and brake lines specific to your 335i/335i xDrive M Sport. While this is a substantial upgrade, it's important to remember that for optimal performance and safety, it's always recommended to have a qualified mechanic perform the installation and to ensure your front brakes are also up to the task of balancing the improved rear stopping power.
