Well I know a lot of you have said clean the wheels, clean the wheels, and race on a clean track. Well I didn’t understand exactly why till last night. I have been trying to tune my youngest sons car for three days(building another one too) and it would not run a good time compared to before our pack race and developed a wiggle. Tried new set of wheels and axle still same thing. Built a whole new car made sure it had perfect drills, axles and wheels. Same result!! Frustrated last night so I cleaned the treads with alcohol and cleaned the track. My cleaning cloth was really dirty afterward. I ran the car again and guess what, no wiggle. What a waste of time!! Long story short listen to others on here and keep wheels and track clean or no matter how well you build your car it will not run right.
