Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted Type3-Black

This Brembo Rear GT Big Brake Kit is designed for the 2015-2018 BMW M3, offering a significant upgrade over the factory braking system. What you get in this kit are two 4-piston GT calipers, two 345x28mm two-piece rotors with a Type 3 slotting pattern, and all the necessary hardware to get them installed. This setup is built to handle the demands of spirited driving and track use, providing more consistent stopping power and better heat management.

The calipers are cast aluminum, which helps keep unsprung weight down while still being strong enough for serious braking. The rotors are a two-piece design, meaning the hat and the friction ring are separate. This allows for better thermal expansion and makes replacement easier down the road. The Type 3 slotting pattern on the rotors is designed to help clear out dust and gas that can build up between the pad and rotor surface, which helps maintain a strong, consistent bite even under heavy braking. The black finish on the calipers gives a clean, performance-oriented look behind your wheels.

When you're looking to get the most out of your M3's braking performance, especially if you plan on hitting the track or pushing your car hard, a big brake kit like this from Brembo is a solid choice. It’s a comprehensive package that addresses the key components needed for an improved braking experience. Remember to consult the manufacturer's installation guide for specific details on mounting and any other components you might need for a complete brake service.
