Evo 123 - Cusco - Type MZ Front LSD 1-Way/1.5-Way
Cusco Type MZ Front LSD, 1-Way / 1.5-Way — Evo 1/2/3
Type MZ is the aggressive half of Cusco's clutch-type range: initial torque is high and lock-up arrives early and hard, which is what you want when the car sees track time and you would rather have the front axle hauling the car out of a corner than a tire lighting up. It is supplied configured as a 1-way, locking on drive only, and the cam can be reset to 1.5-way — that adds a measure of lock on deceleration, which settles the car on corner entry and under trail braking at the cost of some low-speed manners. If your Evo left the factory with an open front differential, order the open-diff Type MZ (LSD 134 A) instead of this one.

- Type MZ: high initial torque, firm and immediate lock-up
