The wiggle is not excessive...but it is there a small bit...the real problem I see on both trucks is the steering racks which are stock...the Blitz is real bad...the SC not to bad...Can't wait to get the new bell cranks!! Thanks for Help and to a great thread!

The weight thing is a little more confusing...I thought using heavier springs in the from was a good way to get more traction in the back.
Do I look for skidding around corners or bad traction when accelerating to add weight in one area or another?
