Here are some ideas to try in order of importance.
1) Check your tires, make sure you are running what others at your track are. Make sure you clean them and sauce them with appropriate sauce if allowed (paragon or Jack the Gripper for odor free tracks). Make sure they aren't too old, usually after 10 runs or if your belt is showing time to replace them. VTA is slower so you may get more runs.
2) make sure nothing is rubbing when you steer at full lock.
3) Make sure your front slipper spool is tight, you should really not be able to turn one tire while holding the other with your hand.
4) make sure your droop is to kit settings, 7mm front and 6mm back.
5) Turn down your dual rate on your radio and/or move your steering bellcrank ackerman position to C.
6) 2 degree of rear toe-in for carpet usually. Too much rear toe will make you loose out of the corner.
7) 6mm front right height, 5mm rear.
8) add a sway bar to the front or go stiffer on the roll bar if you already have it (silver). Front spring is usually 1 or 2 steps stiffer than back, Blue front/Silver back or silver/Green.
Also make sure your rear diff isn't too tight. Tighten it according to AE's instructions.
For your body, you should have some type of rear wing. I don't know VTA bodies, but put whatever wing you can on the back within your club rules.
If its severe its most likely your tires or having no wing. Something major.
Oil could be lighter in the rear, like 45/35 but you should not be spinning because of it.
Make sure you don't have excessive drag brake or something too.
