wide track bearings kit(15-20$), wheel spacers(free), gpm alum knuckles(12$) and alum steering rod(9$) will cure the front end wiggle.
widetrack bearings being the best mod for this..and they will free up some frictional losses so the car will run a little faster and give you slightly longer runtimes.
and then once you do this, you'll want tighter steering, so search the forums for the "tight turns" mod.
