[2.7RACER]

Joe,
Adding a sway bar to the rear will help the front tire lift in the corners. Unfortunately it will also tend to make the rear a bit stiffer and more tail happy.

Reducing rear tire pressure, softening rear shocks, or a smaller rear torsion bar will help the rear looseness.

Conversely stiffening up the front can help to balance the car as well.

Too much added front stiffness will result in understeer. Not what you want at either AX or track.

You indicated the front sway is adjustable.
For the track, I would stiffen the front sways some, stiffen the front shocks, reduce rear tire pressure, or soften the rear shocks. Leave it as is for AX work.
Obviously you don't want understeer. You want balance and predictability.

I would try each of these, at the track, individually first and test. Any one of these might achieve what you are looking for. It may take a little bit of all of them. Test, test, test.

Personally I like a tail happy car for AX work. I tighten my REAR sway for AX's and soften it for the track. Since your FRONT is adjustable, I'd tighten it for track work and leave it as is for AX.

You'll find the answer.
