Cusco Front Type-RS - 1 Way Limited Slip Differential Subaru STI 2004-2021 | LSD 184 C

Cusco's performance limited slip differentials can help in a number of ways. During turning, the inner driven wheel experiences less weight and can spin freely preventing you from putting the power down while upsetting the car. An LSD will force the other wheel to spin at the same rate, maximizing traction on power out. During acceleration, a stock LSD can often be too weak to lock both wheels allowing one to spin. Cusco's LSDs will keep both wheels locked firmly in place to keep the car planted while putting down all your power. Cusco offers two different types of LSDs. The Type-RS utilizes springs to absorb some of the initial torque application on the LSD. This makes for a gentler engagement and smoother transitions. Chatter is kept to a minimum and life is extended. Oil change frequency is also reduced. The Type-MZ does not have springs and engages harder than the RS. By switching the number of clutch plates in the unit, the sensitivity can be set. This would be the cost effective choice.

1 Way - Ideal for FWD and AWD front axles. Activates under acceleration and not on deceleration. When off the throttle, it acts like an open diff allowing for maximum traction in turning and braking. During power on, the LSD engages again ensuring full power is put down.
