Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of select BMW M3 models includes a pair of 4-piston cast aluminum calipers, two 380x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to complete the installation. This kit is designed to significantly upgrade your M3's braking performance, offering improved stopping power and heat management for spirited driving or track use.

Brembo is well-known for its high-performance braking components, and this GT kit is a prime example. The 4-piston calipers are built for strength and consistent pressure application, working in tandem with the larger 380x28mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of warping under extreme heat. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, which is crucial for maintaining braking performance during repeated hard stops. The cast aluminum construction of the calipers helps keep unsprung weight down while providing a solid foundation for the pistons.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. While this kit is designed as a direct fit for the specified M3 models, it's always a good idea to confirm compatibility with your specific vehicle's wheel size, as the larger calipers and rotors may require a minimum wheel diameter. This kit represents a substantial investment in your vehicle's performance and safety, offering a noticeable improvement in braking feel and fade resistance.
