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

This Brembo rear big brake kit includes everything you need to upgrade the stopping performance on your 2015-2018 BMW M3 (excluding CCB models). You get a pair of cast aluminum 4-piston calipers, two 380x28mm two-piece rotors with a Type 3 slotting pattern, and all the necessary hardware for installation. This kit is designed to replace your factory rear braking components with a more robust system, giving you more confidence when you need to slow down quickly.

The calipers are made from cast aluminum, which is strong yet lightweight, helping to reduce unsprung weight. The two-piece rotors feature a 380mm diameter and a 28mm thickness, providing a larger surface area for heat dissipation and braking force. The Type 3 slotting pattern on the rotors is designed to help sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent braking performance even under heavy use. This is a significant upgrade over stock, especially if you plan on tracking your M3 or driving it hard on winding roads.

When installing this kit, you'll want to ensure you have the proper tools and refer to Brembo's installation guide for specific torque values and procedures. It's a good idea to have your brake fluid flushed and replaced with a high-performance fluid at the same time to get the most out of this big brake kit. This kit is a substantial investment in your vehicle's performance and safety, offering a noticeable improvement in braking feel and fade resistance.
