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

If you're looking to significantly upgrade the braking performance of your 2001-2006 BMW M3, this Brembo GT Big Brake Kit is designed for that purpose. This rear kit focuses on providing the stopping power and heat management needed for spirited driving and track use, ensuring your M3 can slow down as effectively as it accelerates.

This kit includes Brembo's well-known 4-piston calipers, which offer a substantial increase in clamping force over the factory setup. The calipers are paired with 2-piece, 345x28mm rotors featuring Brembo's Type-3 slotting pattern. These slots help to vent gases and dust away from the pad surface, maintaining consistent braking performance even under heavy load. The 2-piece rotor design also helps to reduce unsprung weight and manage heat more effectively than a traditional single-piece rotor. The cast iron construction of the caliper bodies is robust and built to withstand the rigors of performance driving.

When installing a big brake kit like this, it's important to ensure you have the correct brake fluid and potentially a brake bleeding kit on hand. This kit is a comprehensive upgrade, and while it's designed to fit your M3, always refer to the manufacturer's installation instructions for specific details and torque specifications. The result is a more responsive and reliable braking system that complements the performance capabilities of your M3.
