I am with Mr P, Oldtimer and a few others and balance mine with a old bubble balancer from a service station, I tried running a set not balanced once and the car hopped all over the track, took them off and balanced them and hopping went away,,I will never run them un-balanced again, mine are also screwed and with tubes.
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
