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

The 380x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent thermal properties and durability under heavy braking. This rear kit is specifically designed for the 2015-2018 BMW M3 models, excluding those with Carbon Ceramic brakes, and features a 4-piston caliper setup. The Type 3 slotted rotor design helps to keep the pads clean and dissipate heat and gas, which is crucial for maintaining consistent stopping power during spirited driving or track use.

This kit includes everything you need to upgrade your rear braking system. The calipers are a robust 4-piston design, offering increased clamping force over stock. The two-piece rotor construction allows for better heat management and can reduce unsprung weight compared to a single-piece rotor. The Type 3 slots are a popular choice for performance applications because they provide a good balance between pad cleaning and rotor surface area, helping to prevent glazing and maintain optimal friction.

When installing this kit, you'll want to ensure you have the proper tools and refer to the manufacturer's instructions for specific details. It's a significant upgrade that can make a noticeable difference in your vehicle's braking performance, especially if you plan on pushing your M3 hard. Consider pairing this rear kit with a front big brake kit from Brembo for a complete, balanced braking system.
