BMW M4 Brake Rotors (2) – Front – EBC SG Racing 2‑Piece Floating SD, Vented, 380mm. OE‑replacement rotors for 2021–2027 BMW M4 (non‑carbon‑ceramic) built for precise, consistent braking.

The two‑piece layout pairs a cast‑iron friction ring with a lightweight alloy hat, linked by stainless bobbins to cut unsprung and rotational mass. Floating SD hardware helps control heat and pad knockback, while the vented 380mm ring (36mm nominal/34mm min) keeps performance stable under repeated stops. Direct 5‑bolt fitment simplifies service; when worn, replace only the outer ring and keep the hat and bobbins to reduce long‑term cost.
