Brembo 01-06 M3 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Silver

If you're looking to significantly improve the stopping power and heat management of your 2001-2006 BMW M3, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory braking system. The larger rotors and multi-piston calipers work together to provide more consistent braking performance, especially under heavy use.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force and better heat dissipation compared to smaller, factory calipers. They work with the 345x28mm two-piece rotors, featuring Brembo's Type-3 slotting pattern. These slots are designed to help clear out brake dust and gases that can build up between the pad and rotor surface, which helps maintain optimal friction and prevents glazing. The two-piece rotor construction allows the rotor ring to expand and contract independently of the caliper mounting hat, reducing the risk of thermal stress and warping over time. The silver finish on the calipers and the slotted rotors give your M3 a distinct, performance-oriented look.

This kit includes everything needed for installation, including the calipers, rotors, mounting brackets, and high-performance brake pads specifically chosen to work with this system. While this is a bolt-on kit, professional installation is recommended to ensure everything is set up correctly for optimal performance and safety. Upgrading your rear brakes with a kit like this is a critical step for any M3 owner looking to maximize their vehicle's performance potential, especially if you plan on track days or aggressive canyon carving.
