Girodisc 370mm Rear Replacement Rotor Rings for BMW G8X M2, M3 & M4 (D2-282)
Genuine Girodisc 370mm Rear Replacement Friction Rings
Restore the performance of your Girodisc rear braking system with the Girodisc D2-282 370mm Rear Replacement Rotor Rings. Specifically engineered for Girodisc's A2-282 two-piece rear rotor assemblies, these genuine replacement friction rings allow you to refresh your brake system without replacing the original aluminium centre hats, reducing servicing costs while maintaining exceptional braking performance.
Manufactured from Girodisc's proprietary high-carbon cast iron alloy, these replacement rings are designed to withstand repeated high-temperature braking while delivering excellent heat dissipation, consistent pedal feel and long-lasting durability. Each kit includes a pair of replacement rings along with new floating hardware, ensuring your Girodisc rotor assemblies continue to perform as intended.
Designed for Girodisc Two-Piece Rotor Systems
The D2-282 replacement rings are designed exclusively for Girodisc A2-282 370mm rear rotor kits. Once your existing friction rings reach their service limit, simply replace the rotor rings while reusing your existing Girodisc aluminium hats.
This modular design is one of the key advantages of Girodisc's two-piece rotor system, providing lower long-term ownership costs and reducing waste without sacrificing braking performance.

Why Replace Only the Rotor Rings?
Girodisc's serviceable two-piece rotor design allows the friction rings to be replaced independently when worn, while retaining the original lightweight aluminium hats.
Benefits include:
- Lower replacement costs
- Reduced workshop downtime
- Retention of lightweight two-piece construction
- Reduced waste compared to replacing complete rotors
- Restored braking performance for road and track use
This modular approach has made Girodisc a popular choice among performance enthusiasts and professional race teams looking for maximum performance with lower long-term running costs.
