Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted Type1-Black

This Brembo rear GT Big Brake Kit is specifically for select 2015-2018 BMW M3 models. It's a comprehensive upgrade designed to significantly improve your vehicle's braking performance, especially under demanding conditions. The kit includes everything needed to replace your factory rear brake setup with a more robust system from a well-known name in braking technology.

At the heart of this kit are the 4-piston calipers, which offer increased clamping force over stock. These are paired with 345x28mm two-piece rotors. The two-piece design allows for better heat management and reduced weight compared to a single-piece rotor, while the slotted surface helps to clear out dust and gas buildup. This combination works together to provide more consistent stopping power and better heat dissipation, reducing the risk of brake fade during spirited driving or track use. The calipers come finished in black for a clean, performance-oriented look.

When installing a big brake kit like this, it's important to ensure all components are fitted correctly according to Brembo's instructions. While this kit is designed as a direct replacement for the factory rear brake system on compatible M3 models, it's always recommended to have a qualified technician perform the installation to guarantee proper function and safety. This kit represents a substantial upgrade for owners looking for the best in braking performance and reliability.
