GiroDisc 2020+ BMW M3/M4 (G80/G82/G83 w/Carbon Ceramic Brakes) Slotted Rear Rings

What you get in this kit are the two rear rotor rings for your 2020 and newer BMW M3, M4, or M4 Convertible (G80, G82, G83) that came equipped with the factory carbon ceramic brake system. These are not full rotor assemblies, but rather the replacement rings that attach to your existing aluminum hats. This is a smart way to get improved braking performance without the cost of a completely new rotor and hat assembly.

GiroDisc is known for making well-built brake components, and these rotor rings are no exception. They are made from a high-carbon iron alloy, which is a strong material that can handle the heat generated during hard braking. The key feature here is the slotting pattern. These slots are specifically designed to help vent gases and heat away from the braking surface. This means you get more consistent stopping power, especially during repeated hard stops, and it helps reduce the chance of brake fade. The slotting also helps to keep the rotor surface cleaner, which can contribute to better pad wear over time.

Replacing just the rotor rings is a common practice when the original rings are worn out but the aluminum hats are still in good condition. This allows you to refresh your braking system with an upgraded component that offers better performance and durability. Make sure you have the correct tools and knowledge for rotor ring replacement, as it involves transferring the rings to your existing hats. If you're unsure, it's always best to consult a professional mechanic.
