2) Requires both wheels to have traction
- stiffly sprung race car can easily lift a wheel at apex as you run over bumps/curb, making it hard to put power down.

They work great as a center diff or a front diff where it's more open-like behavior is critical for control.
Now I am not sure that it was a torsen,but it was a geared type diff rather than a clutch based unit.It would transfer power with one wheel in the ground as we discovered when a codriver backed it into the wall and we had to move it around on a jack using its power.Maybe it was a Quafe?It was 19 years ago so it is a little foggy.
