Brembo 06-08 Z4 M-Coupe/Roadster Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Red

This Brembo GT Big Brake Kit for the rear of your 2006-2008 BMW Z4 M-Coupe and M-Roadster includes everything you need for a significant upgrade to your braking system. You'll get a pair of red 4-piston cast aluminum calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brakes, offering improved stopping power and heat management for spirited driving and track use.

The calipers in this kit are Brembo's GT series, known for their robust construction and performance capabilities. They feature a 4-piston design, which helps distribute braking force more evenly across the larger 345mm rotor, leading to better pedal feel and more consistent stopping. The rotors themselves are a two-piece design, with a cast iron friction ring attached to an aluminum hat. This construction helps reduce weight and allows for better heat dissipation, which is crucial for preventing brake fade during demanding use. The slots on the rotor surface are designed to help clear out brake dust and gases, maintaining optimal contact between the pad and rotor for improved performance.

Installing a big brake kit like this is a substantial modification that can greatly enhance your vehicle's performance and safety, especially if you plan on track days or aggressive driving. The larger rotor surface area and multi-piston caliper work together to provide more clamping force and better heat handling than stock components. While this kit is designed as a direct replacement for the rear axle, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications to ensure a proper and safe setup.
