Brembo 15-18 M3 (CC Brake Eqpt) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Yellow

The 380x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its ability to handle heat and provide consistent friction. This kit is specifically designed for the rear of 2015-2018 BMW M3 models equipped with the CC Brake Equipment. It’s a comprehensive package aimed at significantly improving your vehicle’s braking performance, especially under demanding conditions.

This kit includes four-piston calipers, which offer more clamping force than typical two-piston calipers, translating to quicker stops and better pedal feel. The rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and debris away from the pad surface. This slotting design is crucial for maintaining braking effectiveness during repeated hard stops, preventing fade and ensuring a more reliable performance. The two-piece rotor construction also helps to manage heat more effectively and can reduce unsprung weight compared to a single-piece rotor.

When installing a big brake kit like this, it's important to ensure all components are properly seated and torqued according to the manufacturer's specifications. This kit is a substantial upgrade, and while it's designed as a direct fit for the specified M3 models, always refer to the included installation manual for detailed instructions. The yellow caliper finish adds a distinct visual element to your vehicle's wheel well, complementing the performance enhancements.
