It's hard to do a comparison between the three...If you have a coilover kit you don't need springs, if you have springs you don't need lowering cups...If you have cups it means you're into cosmetic mods only and are cheap.TC330Ci said:Has anyone done a comparison of the H&R springs vs. cup kit vs. coilovers? Interested in differences in handeling/ride and drop compared to stock sport package on a 330Ci (or other).
