Brembo 15-18 M3 (CC Brake Eqpt) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type1-Red

Brembo is well-known for making high-performance braking components, and this Rear GT Big Brake Kit is a prime example of their expertise. If you're looking to significantly upgrade the stopping power and thermal management on your 2015-2018 BMW M3 equipped with the Competition Package (CC Brake Eqpt), this kit is designed to make a substantial difference. It replaces your factory rear braking system with a more robust setup that can handle repeated hard braking without fading.

This kit features a pair of red, 4-piston cast aluminum calipers that offer increased clamping force over stock. Paired with these calipers are 380x28mm two-piece, slotted rotors. The two-piece design allows the rotor friction surface to expand and contract independently of the hat, which can help reduce stress and prevent warping. The Type 1 slots on the rotor surface are designed to help vent gases and heat away from the pad surface, maintaining consistent braking performance even under demanding conditions. The larger rotor surface area also contributes to better heat dissipation.

When installing a big brake kit like this, it's important to ensure you have the correct brake fluid with a high boiling point, as the improved braking performance will generate more heat. This kit is a significant upgrade for drivers who push their vehicles hard and demand the best from their braking system.
