Need some help the back end of my sons car has the wiggles, our race is Tmrw. I am a little conservative on the center of gravity 7/8" so I dont think it could be that and I have 3" of steer in 4', any suggetions. It does seem that its best times are when the car does wiggle but I would think if I could get rid of the wiggles it should speed up?
 
Adjust the steer. More steer and the car won't wiggle. My cars like more than what you've got. Give it more steer till it doesn't wiggle, then backoff a little and find the sweet spot. Then maybe give it a little more steer, other cars on the track can give you a little wiggle. I'm not sure if it's the vibration or aero, or both from the other cars. Just spend some time tunning, make sure your wheel to body gaps are optimal also.
