Brembo 15-18 M3 Excl CC Brake Rr GTS BBK 4Pis Cast 345x28 2pc Rotor Slotted TY3L - Black HA

This Brembo Rear GTS Big Brake Kit includes everything you need to upgrade your braking system: a pair of black 4-piston aluminum calipers, two 345x28mm 2-piece slotted rotors, and all the necessary hardware for installation. This kit is specifically designed for the 2015-2018 BMW M3 models, excluding those with Carbon Ceramic brakes.

The calipers are cast from aluminum, making them strong yet lightweight, which helps reduce unsprung mass for improved handling. Each caliper houses four pistons, allowing for more even pressure distribution across the brake pad and a larger contact area with the rotor. This translates to more consistent stopping power and better heat dissipation under demanding conditions. The rotors are a 2-piece design, meaning the hat and the friction ring are separate components. This design helps manage heat expansion and can make replacement easier down the line. They are also slotted, which helps to sweep away dust and gas that can build up between the pad and rotor, maintaining optimal braking performance, especially during spirited driving or track use. The 345x28mm rotor size offers a substantial increase in surface area compared to stock, further enhancing braking capability.

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 fit for the specified M3 models, it's always a good idea to confirm compatibility with your specific vehicle's wheel size to ensure clearance. This kit represents a significant upgrade for drivers looking for improved braking performance and durability.
