When you increase Diameter and decrease Weight of a shaft, you increase its Critical Speed. The Critical Speed of a rotating shaft is the speed in which it begins to operate with strong resonant vibrations and becomes unstable. In terms of a Sprint Car Drive Shaft, this is when the drive shaft starts to turn into a vibrating jump rope, which typically leads to premature U joint failure.
