The EBC two‑piece SG Racing rear rotor for 2021+ BMW M3/M4 (G80/G82/G87) reduces unsprung rotational mass while offering replaceable friction rings for long‑term value. The floating assembly uses a vented disc and stainless hardware so when the cast iron ring wears you can replace the outer ring only, reusing the hub and bobbins to lower running costs while retaining improved turn‑in, tyre contact and heat management.
