It would add rear spring rate and introduce more oversteer to the car. Since the swaybar acts by resisting twisting of the bar, a very simple way to look at it is to compare the moment of inertia. So assuming same material in the bar, same mounting points, etc. The 19mm bar offers 2x the resistance of a sport 16mm bar and 3.4x of a base 14mm bar. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
