i'm not saying you can't feel the difference, especially at the speeds you tend to drive. just saying that it is an easy thing to live with or without.
also, since some people i am talking to seem to be under the impression that doing the little things to a 15second car won't help, i would say that you do the mods you can afford or you have available to improve your car. if that means starting with the free and cheapest mods, that is what you have to do.
