Kid, you have a valid point. However, i must point out that while coilovers do subject one to a much firmer ride, so do many of the other "mods" or "upgrades" that a lot of you guys so eagerly slap onto your cars. Adding 17 or 18 inch wheels with a profile of 45 or less will certainly induce a much more harsh driving experience. Also, sport shocks and lowering springs are not going make a huge difference in comfort versus coilovers. Yes it is true that for everyday driving, coilovers are not going to make a big difference versus sport shocks and springs, but neither would a CAI, sport exhaust, short shift kit, or any of the other mods that we all love. All of these can only be appreciated when driving a car in a spirited fashion.
So, for one to make the claim that coilovers aren't worth the difference, you should also forget adding a CAI, K&N, sport exhaust, better plug, improved sway bars, or anything else that constitutes a moderate improvement in performance!
