Replace your Quaife with an ATX and you won't care so much if you lift a
wheel. Quaife's are torque-biasing diffs, ATX's are true limited slips.

I think the main reason LBCs lift wheels is that the roll center of the
front is different than the roll center of the back. Real suspension gurus
might be shaking their heads at such twaddle, but I think it's true.
Usually that means bringing the front roll center up, though with your
rotoflex rear suspension you might be able to bring the rear lower. I
don't know much about them. Theoretically a heavier rear sway bar will
force the outside wheel down, but in practice, that much force will
increase the rear end steer, make the car too tight and will probably
screw up the turn in. Not what you have in mind for autoX. 

You could also get a passenger to hang their ass out like a sidehack.

Hey Guys and Gals,

I have been having a ball figuring out the limits of Tiny Tim (the
Autocross Spit) now that I have the S2000 engine performing as it is
supposed to. 
 
My most immediate problem is that on a hard corner, I am lifting one of
the rear wheels.  

Bear in mind that I have a Rotoflex rear suspension and a Quaife LSD.
What recommendations do you have about how to keep all four tires firmly
planted on the pavement?

I eagerly anticipate all the learned replies!

Regards,
Joe (C)
