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

If you're looking to significantly improve the stopping power and heat management of your performance vehicle, this rear brake kit from Brembo is a solid choice. Designed for specific BMW M3 models, this kit replaces your factory rear brakes with a more robust setup that can handle harder driving and repeated stops without fading. It’s a substantial upgrade for anyone who pushes their car on the track or enjoys spirited driving on the street.

At the heart of this kit are the 345x28mm two-piece rotors. These are slotted with Brembo's Type 3 pattern, which helps to vent gases and heat away from the pad surface, keeping your brakes cooler and providing a more consistent bite. The rotors are cast iron for durability and are designed to be a two-piece assembly, which can help reduce weight and manage heat expansion. The calipers are a 4-piston design, offering more clamping force than a typical factory caliper. This increased force, combined with the larger rotor surface area, translates directly into shorter stopping distances and better control, especially under demanding conditions. The calipers come finished in black, giving your wheels a clean, performance-oriented look.

This kit is engineered as a direct replacement for the specified M3 models, meaning it's designed to fit without major modifications. You'll want to ensure you have the necessary tools and knowledge for a brake system overhaul, or consider having a professional mechanic handle the installation. Upgrading your rear brakes like this is a critical step for any performance build, ensuring you have the stopping power to match your engine's output and the confidence to brake later and harder.
