Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Drilled-White

This Brembo GT Big Brake Kit for the rear of your 2015-2018 BMW M3 (excluding CC models) includes everything you need to significantly upgrade your braking system. You get a pair of cast 4-piston calipers, two 380x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes with a much more robust setup, offering a substantial improvement in stopping performance and fade resistance, especially during spirited driving or track use.

Brembo is well-known for its high-performance braking components, and this GT kit is a prime example. The calipers are made from cast aluminum, which is strong yet lightweight, and feature a 4-piston design to provide more clamping force than stock. The two-piece rotors are a notable upgrade; the floating design allows the rotor to expand and contract independently of the hub, reducing the risk of warping. The 380x28mm size offers a larger surface area for better heat management, and the drilled pattern helps vent gases and heat away from the pad surface, keeping your brakes cooler and more effective under heavy load. This means more consistent braking performance when you need it most.

Upgrading to a big brake kit like this is a significant undertaking, but the results are well worth it for drivers who demand more from their vehicle's braking system. Ensure you have the proper tools and refer to the manufacturer's installation instructions for detailed guidance. This kit is a solid option for anyone looking to enhance their M3's track capability or simply achieve a higher level of confidence in their daily driving.
