This Cusco 1.5-way limited-slip diff replaces the factory front differential.
In the RS Model, the activation pressure is applied to the same direction of the initial torque with the utilization of a coil spring. Therefore, the initial torque is set lower than the MZ model enables a smoother and quicker initial clutch plates engagement from a non operational to a fully functioning state even despite a low initial torque rating is set. The virtues of a low initial torque setting is that it enables a smooth turn even while the LSD mechanism is not activated. Because of the coil spring design, it provides overall gentle and stable operation.
What is Spec-F?
An option on most Cusco LSDs, Spec-F denotes a flat-friction disc. Versus the standard diffs' friction clutch discs, the Spec-F friction discs result in smoother, gentler, and milder engagement of torque. Spec-F is ideal for most street cars and casual track drivers and reacts smoother to gentle throttle inputs. Non-Spec-F diffs will engage more aggressively for quicker torque engagement, ideal for inducing oversteer or sharpening corner entry in the hands of skilled drivers but is not the most stable or easy-going setup for more casual enthusiasts.
