I have two earlies which do not "jack".
The Bill Thomas/Doug Roe car and my personal 63 Spyder both have large 
front and rear anti roll bars----
"No roll, no tuck"
    I think that I have proven the above by success on the track and 
autocrosses.

Smitty Says;  I have to jump in here because I think most of you don't 
understand axle jacking.  Yes the loaded "outer" wheel does push up 
into the wheel well initially but as the lateral Gs increase it starts 
coming back out again .  The axle wheel assy is working as a lever on a 
line from the U joint to the tire tread.  If the tread has enough bite 
the loaded wheel will fold up under the car lifting it, (Jacking the 
car) until the tire is on it's sidewall "and in a soft tire condition" 
the rim will dig into the pavement.  At that point you can kiss it 
goodby.  Rebound straps are to prevent that situation by keeping the 
tread on the pavement even though it may be sliding.  Fire up your 
flame throwers but I am sure I am on solid ground with this.
