Hey guys, I was getting tired of people not knowing what size different swaybars were and figured we might as well have this thread somewhere.

Increasing Swaybar Diameter - How Much Will It Help?
It's not as simple as it seems when you look as increasing swaybar thickness. Torsional rigidity increases exponentially with thickness.
[(Larger Diameter^4)/(Smaller Diameter^4)]*100= Percent Increase in Stiffness
Examples:
From 16mm to 18mm (assume both are hollow, with proportional inner diameters)
[(18^4)/(16^4)]*100= 160% increase in torsional rigidity
From 20mm to 24mm (assume both are solid)
[(24^4)/(20^4)]*100= 207% increase in torsional rigidity
From 17mm to 24mm (17mm is not solid, so the increase is actually GREATER than this simplified calculation)
[(24^4)/(17^4)]*100= 397% increase in torsional rigidity
