Brembo 15-18 M3 (CC Brake Eqpt) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type1-Yellow

If you're looking to significantly upgrade the braking performance on your 2015-2018 BMW M3 equipped with the Competition Package, this Brembo Rear GT Big Brake Kit is a serious consideration. This kit replaces your factory rear brakes with larger, more capable components designed to handle increased heat and demand, crucial for spirited driving or track use. It features robust 4-piston calipers and a substantial 380x28mm two-piece rotor design, which work together to provide more consistent and powerful braking.

The calipers are cast from durable materials and finished in a striking yellow, housing four pistons that apply even pressure across the larger, slotted rotors. These rotors are not just about size; the slots are specifically designed to help vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade during hard braking. The two-piece construction of the rotor allows for better heat management as the aluminum hat can dissipate heat independently from the iron braking surface, reducing the risk of warping. This setup is built to offer a notable improvement in stopping distance and pedal feel compared to stock equipment.

This kit is designed as a comprehensive upgrade, aiming for a direct fitment where possible, though professional installation is always recommended for big brake kits to ensure all components are correctly seated and functioning. You'll want to ensure you have adequate clearance within your wheels for the larger calipers and rotors; check the manufacturer's specifications for wheel fitment details. This Brembo kit represents a significant investment in your vehicle's performance and safety, offering a substantial leap in braking capability.
