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

The 345x28mm, two-piece rotors in this Brembo GT Big Brake Kit are a key component, designed to handle the heat generated during spirited driving and track use. This kit is specifically for the rear of the 2001-2006 BMW M3, offering a substantial upgrade over the factory braking system. It features robust 4-piston calipers cast from high-strength aluminum, paired with these substantial rotors, all engineered by Brembo to provide a significant improvement in stopping power and heat management.

The Type-3 slotting pattern on the rotors is not just for looks; these slots help to vent gases and dust away from the pad surface. This action helps maintain consistent braking performance, especially under heavy load, reducing the chance of fade. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a traditional one-piece rotor. This design also helps to reduce unsprung weight compared to a comparable one-piece rotor setup.

When installing this kit, you're looking at a significant upgrade that will change the feel and performance of your M3's braking system. It's designed to be a direct replacement for the factory components, though it's always recommended to consult the manufacturer's installation guide for specific details and torque specifications. This kit is a popular choice for M3 owners who participate in track days or autocross events, or simply want the confidence of knowing their car can stop hard and reliably, time after time.
