Brembo 01-06 M3 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type-1-Black

If you're looking to significantly upgrade the stopping power on your 2001-2006 BMW M3, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to give your M3 improved braking performance, especially under demanding conditions where heat and fade can become an issue. It replaces your factory rear brake setup with a much more robust system, featuring larger rotors and powerful calipers.

At the heart of this kit are the 345x28mm two-piece rotors. The two-piece design helps manage heat more effectively than a single-piece rotor, as it allows for better expansion and contraction. These rotors are also slotted with Brembo's Type-1 pattern, which helps to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern is known for its effectiveness in maintaining consistent braking performance, even during repeated hard stops. The calipers themselves are Brembo's cast 4-piston GT calipers, finished in a sleek black. These larger, multi-piston calipers apply more even pressure across the brake pad, leading to better clamping force and more controlled braking.

This kit includes everything you need to get your M3's rear brakes upgraded. You'll find the calipers, the two-piece rotors, caliper mounting brackets, and high-performance brake pads specifically chosen to work with this system. It's a comprehensive package aimed at delivering a noticeable improvement in braking feel and fade resistance for your M3.
