Cusco Rear Type MZ – 2 Way Limited Slip Differential Subaru STI 2004-2014


Cusco LSD MZ R180 GC8 GDB GRB GVB Rear 2WAY(1.5&2W)


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.

2 Way – Ideal for RWD cars and AWD rear axles. Ideal for high speed track use and drifting. Activates on both acceleration and deceleration. This is preferable for drifters as the LSD behaves the same regardless of erratic throttle input, and lets you keep the wheels spinning all the way through a corner. Some caution is required as suddenly lifting can unsettle the car.
