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

This Brembo GT Big Brake Kit for the rear of your 2001-2006 BMW M3 includes everything you need to significantly upgrade your braking system. You get a pair of four-piston GT calipers, two 345x28mm two-piece slotted rotors, caliper mounting brackets, and all the necessary hardware to get them installed. This kit is designed to replace your stock rear brakes with a much more robust setup, offering improved stopping power and heat management for spirited driving or track use.

The calipers are cast aluminum, which keeps weight down while providing a solid foundation for the pistons. The two-piece rotors are a notable upgrade, featuring a floating design where the rotor ring is separate from the hat. This allows for better thermal expansion without inducing stress or warping, and the cast iron rotor rings are slotted to help vent gases and dust away from the pad surface, maintaining consistent braking performance even under heavy load. The black finish on the calipers and the Type-1 slotting pattern add a distinctive look to your M3.

Upgrading your rear brakes with a kit like this is a substantial modification. Ensure you have the proper tools and knowledge for installation, or consider having a professional mechanic handle it. This kit is a popular choice for M3 owners looking to enhance both the performance and aesthetics of their vehicle's braking system.
