Genuine Mitsubishi Front Brake Disc MR389724 – Lancer VIII / Galant / Eclipse (Vented) restores factory braking feel with exact OE geometry, refined pedal response, and disciplined NVH control. The vented friction ring and precise vane design improve heat rejection, while tight runout and disc-thickness tolerances reduce pulsation risk. A protective coating on non-swept areas fights corrosion, easing future rotor removal and preserving clean aesthetics behind open wheels. Machined faces promote quick, even pad transfer for quieter torque and consistent deceleration in city traffic or highway descents. With the correct hub bore, hat offset, and bolt pattern, installation is straightforward. Pair with quality pads, fresh hardware, and DOT 4 fluid to enjoy smooth, predictable stopping and long, low-maintenance service.
