Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type1-Red

This Brembo Rear GT Big Brake Kit gives you a complete set of performance braking components designed for specific BMW M3 models. Inside this kit, you'll find a pair of red 4-piston cast iron calipers, two 380x28mm two-piece rotors with a Type 1 slotting pattern, and all the necessary hardware to get them installed. This is a substantial upgrade over stock, aimed at drivers who demand more from their braking system, especially during spirited driving or track use.

The calipers are constructed from cast iron, a material known for its strength and heat dissipation, and feature a 4-piston design. This larger piston area allows for more even pressure distribution across the brake pad, leading to 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 reduce weight and allows the rotor to expand and contract more freely with heat, which can help prevent warping. The 380mm diameter and 28mm thickness provide a larger surface area for heat absorption and dissipation, crucial for maintaining performance under heavy braking. The Type 1 slotting pattern on the rotors helps to sweep away dust and gas that can build up between the pad and rotor, ensuring consistent contact and improved braking performance, especially in wet conditions or during repeated hard stops.

When installing a big brake kit like this, it's important to ensure you have the correct brake fluid and pads that are compatible with the caliper and rotor setup. Refer to the manufacturer's installation guide for specific details on fluid types and any other recommended components. This kit is a significant investment in your vehicle's performance and safety, offering a noticeable improvement in braking response and endurance.
