G80 failure?

There is bizzare information in this thread.
Here are some facts about the G80:
- It has clutches just like a limited-slip differential does.
- Instead of locking in response to input torque, a G80 locks in response to axle speed difference.
- The G80 is self-energized, there is a ramping mechanism that uses input torque to apply force to its clutches.
- Alxe speed difference is detected a centrifugal flyweight that spins on its own shaft inside the differential housing. If that shaft reaches a high enough speed the flyweights hit a detent and the shaft locks up causing the ramps to rotate and lock up the clutches.
A G80 will only lock up AFTER wheelspin is already taking place. It cannot prevent wheelspin like a true limited-split differential can.
A G80 can lock up with one wheel totally in the air meeting no rotational resistance, a Limited Slip must be under torque to lock up.
The G80 is not a true mechanical "locker", nor is it a "limited slip", it's a hybrid between the two.
