Brembo 15-18 M3 (CC Brake Eqpt) Rr GTR BBK 4Pis Billet 380x28 2pc Rotor Slotted Type3-Nickel

If you're looking to significantly upgrade the braking performance on your 2015-2018 BMW M3 equipped with the Competition Package (CC Brake Eqpt), this Brembo Rear GTR Big Brake Kit is a serious consideration. This kit is designed to provide a substantial improvement in stopping power and heat management, crucial for spirited driving and track use where factory brakes can reach their limits. The GTR series represents Brembo's commitment to high-performance braking, offering components that are both robust and refined.

At the heart of this kit are the 4-piston billet aluminum calipers, known for their strength and light weight, which clamp down on massive 380x28mm two-piece rotors. These rotors feature a Type 3 slotting pattern, which is engineered to help vent gases and dust away from the pad surface, maintaining consistent friction and reducing fade during prolonged braking. The two-piece design also helps manage heat by allowing the rotor hat to expand and contract independently from the friction ring. The nickel finish on the rotors adds a layer of corrosion resistance and a distinct look.

Installing a big brake kit like this is a significant undertaking, and it's important to ensure you have the necessary tools and knowledge, or to have it professionally installed. This kit is designed to be a direct replacement for the factory components, but it's always recommended to consult the manufacturer's installation guide for specific procedures and torque specifications. The result is a braking system that offers improved pedal feel, greater fade resistance, and the confidence to push your M3 harder.
