for the bar itself, stiffness is proportional to the 4th power of the diameter of the bar.
of course, the flexiblilty of the bushings and links take a little of the increase away.
(18/17)^4 = 1.26 = 26% stiffer than non-sport MCS
(23.5/22.5)^4 = 19% sttiffer than non-sport MCS
(18/16)^4 --------60% stiffer than non-Sport MC
(23.5/21.5)^4 -- 43% stiffer Than non-Sport MC |
