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

This is the Brembo Rear GT Big Brake Kit for the 2001-2006 BMW M3. It's a comprehensive upgrade designed to significantly improve your M3's braking performance, especially under demanding conditions. The kit includes everything you need to replace your stock rear braking system with Brembo's renowned performance components, offering a substantial increase in stopping power and heat management.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over the factory units. These calipers work with 345x28mm two-piece rotors. The rotors are drilled, which helps to dissipate heat and gasses, contributing to more consistent braking performance. The two-piece design allows for better thermal management and can simplify rotor replacement down the line. Brembo is well-known for its braking systems, and this kit represents their GT (Gran Turismo) line, aimed at drivers who push their vehicles hard and demand reliable, powerful braking.

When installing a big brake kit like this, it's important to ensure all components are properly seated and torqued according to Brembo's specifications. This kit is designed as a direct replacement for the factory rear brake system on the specified M3 models, making installation as straightforward as possible for a performance upgrade. You'll notice a significant difference in pedal feel and fade resistance, particularly during spirited driving or track use.
