Full 2-way helical MZ LSD for the FC3S/FD3S rear end — locks under both acceleration and deceleration. On a rotary car this means the rear stays planted under trailing-throttle and stays planted on power, which changes how the car rotates through corners significantly.
More committed setup than the 1-way; works great if you're already comfortable with the car's balance and want more stability under all phases.
