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

This is the Brembo Rear GT Big Brake Kit for your 2015-2018 BMW M3, specifically excluding models with Carbon Ceramic brakes. Brembo is well-known for its high-performance braking systems, and this kit is designed to significantly improve your M3's stopping power and heat management. It features a 4-piston caliper design, a substantial 380x28mm two-piece rotor, and a vibrant fluorescent yellow finish on the calipers.

The kit includes Brembo's GT calipers, which are cast from aluminum for a good balance of strength and weight. These calipers house four pistons, allowing for more even pressure distribution across the brake pad and a more consistent pedal feel, especially under heavy braking. The two-piece rotor design is also a key feature; the cast iron friction ring is attached to an aluminum hat. This construction helps to reduce unsprung weight and allows the rotor to expand and contract more freely with heat, which can help prevent warping. The rotors in this kit are slotted with Brembo's Type 3 pattern, which helps to vent gases and heat away from the pad surface, maintaining optimal braking performance even during repeated hard stops.

When installing a big brake kit like this, it's important to ensure you have the correct brake fluid and potentially upgraded brake lines to take full advantage of the new hardware. This kit is a substantial upgrade for drivers looking for improved track performance or more confidence during spirited driving. The fluorescent yellow caliper finish adds a unique visual element to your vehicle's wheel well.
