Shorten the IC.. keep it low but shorter... try it
in the 35" to 45" range.... without knowing the CG
of the car thats the best I can offer

Not trying to hijack, just want more clarification on your comment to shorten the IC
How do you shorten the IC? Do you drop the top front bar or raise the lower front bar or both?
thanks
Jerry

what rpm are you launching at?

If you lower the front top bar you shorten the IC and
still keep the IC height about the same... also if
the rear points are farther away from the axle on
the holes it will tend to wheel stand(greater leverage)
and the farther out they are will move the front
points farther(bigger wheel stands)
