disconnect unit

The 'disconnect' unit is a 'freewheel':

Mazda 323 GT Turbo 4WD

You forgot the Mazda 323 1.6 GT Turbo 4WD! (and/or 1.8 GTX)

We are again on a full-time AWD System with planetary gear center differential to split engine torque, electrically lockable via a button on the console that would have activated a Viscous Coupling unit.

Before 1990:
- Normal torque split 50/50
- 185/60R14 performance tires on 5.5J-14 alloy wheels

From 1990:
- Normal torque split of 43/57 (for a rear-wheel-drive feel) could be varied to 60/40
-195 / 60R-14 performance tires
