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

This Brembo GT Big Brake Kit for the rear of select BMW M3 models includes a pair of 4-piston cast iron calipers, two 380x28mm two-piece rotors with a Type 3 slotting pattern, and all the necessary hardware for installation. This kit is designed to significantly upgrade your M3's braking performance, offering more stopping power and better heat management than the factory setup. The larger rotors and multi-piston calipers work together to distribute braking force more evenly and dissipate heat more effectively, which is crucial for maintaining consistent performance during spirited driving or track use.

The calipers are crafted from cast iron for durability and feature a 4-piston design, which allows for more even pad pressure across the rotor surface. This translates to improved braking feel and control. The two-piece rotor construction, with a 380x28mm braking surface, combines a cast iron friction ring with an aluminum hat. This design not only reduces unsprung weight but also helps to manage thermal expansion, preventing rotor warping under heavy use. The Type 3 slotting pattern on the rotors is specifically chosen to help sweep away dust and gas buildup, ensuring optimal pad contact and consistent braking performance, even in demanding conditions. The black finish on the calipers adds a clean, performance-oriented look to your vehicle.

When installing this kit, it's important to follow the manufacturer's instructions carefully, as it involves replacing major braking components. You may also want to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities. This Brembo kit is a substantial upgrade for any M3 owner looking for a noticeable improvement in braking performance and reliability.
