Brembo 15-18 M3 Excl CC Brake Rr GTR BBK 4Pis Billet 345x28 2pc Rotor Drilled-Nickel

Brembo is well-known for making high-performance braking components, and this rear GTR Big Brake Kit is a prime example of their expertise. If you're looking to significantly upgrade the stopping power on your 2015-2018 BMW M3 (excluding models with CCB - Carbon Ceramic Brakes), this kit is engineered to provide a substantial improvement over stock.

This kit includes a pair of 4-piston billet aluminum calipers, which are lighter and stronger than cast alternatives, offering improved rigidity for consistent pedal feel. They work with 345x28mm two-piece rotors. These rotors are drilled to help dissipate heat and reduce weight, and they feature a nickel finish to resist corrosion. The two-piece design allows for better thermal management and easier replacement of the rotor ring in the future. This setup is designed to offer more clamping force and better heat handling, crucial for spirited driving or track use where brake fade can be a serious issue.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the calipers and rotors within your wheels. While this kit is designed as a direct replacement for the factory braking system components, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications. This kit is a serious upgrade for those who demand the best from their vehicle's braking system.
