The EBC Ultimax OE‑style front rotor for 2005–2010 Chevrolet Cobalt 2.2 (4‑lug) combines vented OE construction with progressively angled slots to reduce air noise while drawing cool air across the disc. Slots help eject dust and debris to maintain pad bite and prolong pad life. This vented 256mm front disc is 24mm thick with four bolt holes and a 60mm center bore for direct replacement.
