When I drive the car into a corner, it will understeer, and I find myself getting on the throttle to kick the back end round. I've been having a think about this, and can't think of any setup theory that will resolve this (my one idea is it being an antisquat issue as it seems the steering is throttle sensitive, however maybe the oversteer is only occuring due to breaking rear traction, - but why doesn't it break frint traction?).
Hopefully some more knowledgable ooplers will have a better idea.
This problem occurs whether running a diff or one way, with different ackerman angles. I am currently running long wheelbase (to try and counter the understeer) and 1deg antisquat.
Thanks in advance for any ideas. Chris P.

I would say you need to try shorter wheelbase. If you shorten the wheelbase you will actually increase the amount of steering at initial turn into the corner, and, obviously give you more rear traction when you apply the throttle.
Also if your car is very light you could add a few lead weights towards the rear of the car, this will also improve "turn in" and give more rear traction.
All this assumes that you have a good base setup, which I would suggest would be a little softer than your normal setup.
