Limited Slip Differential for the Front a Subaru Impreza STI GDB
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.
The RS Springs sit inside the pressure rings which helps engage the rear lock and the number of springs can be added or subtracted for personal customization.
Type MZ limited slip differential is designed where the activation pressure opposes the direction of the initial torque with the utilization of the cone spring. The LSD operation first becomes engaged when the opposing pressures start working against one another.
The Type MZ features the highest rated initial torque rating than the rest of any other Cusco LSD models. This is due to the high pressure cone spring which engages full clutch pack lock at a linear rate.
