Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Drilled-Yellow

This Brembo Rear GT Big Brake Kit is specifically for the 2015-2018 BMW M3. It's designed to give your M3 a significant upgrade in braking performance, especially if you're pushing the car hard on the track or just want a more confident feel on the street. The kit includes everything you need to replace your stock rear braking system with a much more robust setup.

At the heart of this kit are the Brembo 4-piston calipers, which offer more clamping force than the factory units. These calipers work with 345x28mm two-piece rotors that are drilled for better heat dissipation. The drilled pattern helps to vent gases and moisture away from the pad surface, which means more consistent braking performance, especially during repeated hard stops. The two-piece rotor design also helps manage heat and can make future rotor replacements simpler. The calipers come in a distinctive yellow finish, adding a visual flair to your wheels.

When installing a big brake kit like this, it's important to ensure all components are properly fitted and bled according to Brembo's instructions. This kit is a substantial upgrade, and it's designed to work as a complete system to provide a noticeable improvement in your car's ability to slow down. You'll likely feel a difference in pedal feel and overall stopping power.
