Brembo 12-15 335i xDrive Exc MSport Brakes Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot Type3-Silver

If you're looking to significantly upgrade the braking performance on your 2012-2015 BMW 335i xDrive (excluding M Sport models), 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 for demanding use, offering improved stopping power and heat management. It's built around a set of four-piston calipers paired with large, two-piece, slotted rotors that work together to provide consistent and powerful braking, even under heavy load.

The calipers themselves are cast from high-strength aluminum, a material chosen for its ability to handle heat while keeping weight down. They house four pistons, which apply more even pressure across the brake pad surface compared to smaller factory calipers. This leads to better pad wear and more effective braking force. The rotors are a two-piece design, measuring 345x28mm, with a floating hat construction. This design allows the rotor ring to expand and contract freely with temperature changes, reducing the risk of warping and ensuring consistent contact with the pads. The Type 3 slotting pattern on the rotor surface is a notable feature; these slots help to vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade during repeated hard stops.

This kit includes everything you need to perform the rear brake upgrade, including the calipers, rotors, and necessary hardware. It's a comprehensive package for enthusiasts seeking a substantial improvement in their vehicle's braking capabilities. Proper installation is key to realizing the full benefits of this system, so refer to the manufacturer's instructions for detailed guidance.
