The EBC Ultimax slotted front rotor set for 1980–1982 Rover SD1 is an OE-style vented disc specified at 258mm diameter and 24mm thickness. The Ultimax design uses progressively angled slots to pull in cool air for reduced operating temperatures while minimizing air noise commonly associated with slotted rotors, helping maintain pad grip and reduce dust for smoother, quieter braking.
