The differential in our '65 Greenbrier was rebuilt with a posi carrier and 
I can reaffirm lclc's observations. Wheel up=no go. The trick to faster 
times is to keep all the wheels [mostly] on the ground unless you are 
"coasting" though some tight turns.  A turn tight enough to lift a wheel 
really scrubs off the speed.

At one autocross I observed lclc get his GB camper (with the Vista Cruiser 
roof) up on two wheels--the inside rear was about 4" off the ground when 
the inside front came up about 1/4." It looked impressive, but lclc was 
nowhere close to rolling it over.

Now then, driving along in an FC at 80 MPH and making a sudden swerve might 
be a different story....
