The Cusco Type-RS 1-way limited-slip differential is a direct-replacement rear LSD for Mitsubishi Lancer Evolution models 1–10 without AYC, tuned to improve traction and cornering balance. Specified with a PPFC 55/0 curve and a high initial preload of roughly 14–16 kg, it favors strong engagement under acceleration to reduce wheelspin and help maintain driveable control during spirited driving.
