some things i would try....
first...
add some weight to the rear of the car
decrease ackerman (increase the angle of the steering rods)
if that doesnt help, try these in this order:
soften front springs or lean in front shocks
soften front sway bar
more front camber or less rear camber...
more rear droop
lower front roll center or raise rear roll center
Start with these... ONE CHANGE AT A TIME!
