Tips for Forward Traction (acceleration out of the corners)
less rear antisquat (change the pill on the front arm mount in the rear end)
Stand the rear shocks out one hole on the tower
Try going up 1000wt in the rear diff
Check rear ride hight 28-30mm
Less front Caster
Shorter Wheel Base
Those adjustments are usually what I will look to do for forward traction.
Brand new cars usually take a while to break in and gain traction especially buggies with CVD's. Be aware that if you put brand new CVD's in the rear, expect a loss of traction till they break in a little.
