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

This Brembo GT Big Brake Kit for the rear of your 2015-2018 BMW M3 (excluding CC models) includes everything you need for a significant upgrade to your braking system. You get a pair of Brembo 4-piston cast iron calipers, two 380x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes with a more robust setup, offering improved stopping power and heat management for spirited driving and track use.

The calipers are a well-built 4-piston design, which helps distribute braking force more evenly across the larger 380x28mm two-piece rotors. These rotors feature a slotted surface, Type 1 pattern, which is effective at clearing out dust and gas that can build up between the pad and rotor surface during hard braking. This slotting helps maintain consistent pad contact and reduces the risk of brake fade, especially under demanding conditions. The two-piece rotor design also helps manage heat more effectively by allowing the rotor ring to expand and contract independently of the hat, reducing the chance of warping.

Installing a big brake kit like this is a substantial modification that can make a noticeable difference in how your car feels when you slow down, particularly during repeated hard stops. While this kit is designed as a direct replacement for the factory rear brake components on the specified M3 models, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications. This kit is a solid option for M3 owners looking to enhance their vehicle's braking performance for track days or aggressive street driving.
