Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted Type1-Silver

This Brembo Rear GT Big Brake Kit starts with a 4-piston caliper cast from aluminum, designed to offer a solid and consistent pedal feel even under heavy use. The kit includes 345x28mm two-piece rotors, featuring a Type 1 slotting pattern that helps keep the pad surface clean and reduces the risk of cracking by allowing for thermal expansion. These rotors are specifically engineered for performance driving, offering improved heat dissipation compared to standard equipment.

The calipers themselves are a notable upgrade, providing more clamping force and a larger surface area for the brake pads. This translates to more effective braking, especially during repeated stops or when carrying extra weight. The two-piece rotor construction is also a key advantage; it allows the rotor to expand and contract more freely with temperature changes, which helps prevent warping and ensures more even pad wear over time. The silver finish on the calipers adds a clean, performance-oriented look behind your wheels.

When installing this kit, you'll find that Brembo parts are generally well-regarded for their fit and finish, aiming for a direct replacement where possible, though specific vehicle modifications might be needed depending on your exact M3 model. This kit is a significant upgrade for anyone looking to maximize their vehicle's braking performance, offering a substantial improvement in stopping distance and fade resistance. It's a well-built system designed for those who demand more from their brakes.
