Brembo 15-18 M3 Excl CC Brake Rr GTS BBK 4Pis Cast 345x28 2pc Rotor Drilled-Black HA

Brembo is well-known for making high-performance braking components, and this rear brake kit for the 2015-2018 BMW M3 is a prime example of their expertise. If you're looking to significantly upgrade your M3's stopping power, especially for track use or spirited driving, this kit is designed to make a notable difference. It replaces your factory rear brakes with a more robust system that can handle higher temperatures and demands.

This kit includes a pair of cast aluminum 4-piston calipers, which offer more clamping force than stock calipers. Paired with these are 345x28mm two-piece rotors. The two-piece design helps manage heat more effectively, as the rotor ring can expand and contract independently of the hat, reducing the risk of warping. The rotors are drilled, which helps to dissipate heat and gases, keeping the pads in better contact with the rotor surface for consistent braking. The black finish on the calipers and hats adds a clean, performance-oriented look to your vehicle.

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 replacement for the specified M3 models, it's always a good idea to confirm compatibility with your specific vehicle's wheel size to ensure proper clearance. This kit is a substantial upgrade for drivers who push their M3s hard and demand reliable, powerful braking performance.
