Brembo 15-18 M3 Excl CC Brake Rr GTR BBK 4Pis Billet 345x28 2pc Rotor Slotted Type3-Nickel

This Brembo GTR rear brake kit includes everything you need to upgrade your 2015-2018 M3's braking performance. You get a pair of 4-piston calipers, billet aluminum caliper hats, and two-piece rotors measuring 345x28mm. The rotors are slotted with Brembo's Type 3 pattern and finished with a nickel plating for corrosion resistance. This kit is designed for serious performance driving, offering improved stopping power and heat management.

The GTR calipers are forged from billet aluminum for a strong yet lightweight construction, and they feature a 4-piston design that applies even pressure across the brake pads. This helps to reduce pad wear and improve braking consistency. The two-piece rotor design, with its floating hat and rotor assembly, allows for thermal expansion without inducing rotor distortion, which is crucial during repeated hard braking. The Type 3 slotting pattern on the rotors is specifically designed to help vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade.

This kit is a significant upgrade for track day enthusiasts or anyone who demands the best from their M3's braking system. While installation is straightforward for experienced mechanics, it's important to ensure all components are properly torqued and bedded according to Brembo's instructions to achieve optimal performance and longevity. This kit is a substantial investment in your vehicle's safety and performance.
