Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Red

This is the Brembo Rear GT Big Brake Kit for your 2015-2018 BMW M3, specifically designed for models excluding the Carbon Ceramic option. If you're looking to significantly upgrade your M3's braking performance, this kit is a serious step up from the factory setup. It features a robust four-piston caliper design paired with large 380x28mm two-piece rotors, all built to handle the demands of spirited driving and track use.

The calipers themselves are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Inside, you'll find four pistons per caliper, working together to apply even pressure across the brake pad surface for improved stopping power and feel. The rotors are a two-piece design, meaning the aluminum hat is separate from the cast iron friction ring. This construction helps manage heat expansion and reduces the overall weight compared to a single-piece rotor of the same size. These rotors are slotted with Brembo's Type 3 pattern, which is known for its effectiveness in clearing out dust and gas that can build up between the pad and rotor surface, ensuring consistent performance even under heavy braking.

This kit is a comprehensive solution for enhancing your M3's braking system. It includes everything needed to install the new calipers and rotors, offering a noticeable improvement in stopping distance and fade resistance. For installation, you'll want to refer to the manufacturer's instructions to ensure proper fitment and torque specifications, as this is a significant upgrade to your vehicle's braking components.
