The EBC Ultimax OE-style rear rotors for 1983–1985 BMW 318 1.8 (E30) offer slotted design benefits in an OE-compatible disc. Progressive slots aid cooling by pulling in air to lower rotor temperatures and help clear dust and debris from the pad face, which supports steady pad grip and can reduce vibration. These rear rotors are specified as replacement discs to match OE dimensions while providing improved thermal and debris-management performance.
