I've got S-techs on my Cavalier and an Accord. They're pretty decent for a cheap spring. I've got them riding on KYB AGX's right now and it's pretty stiff. (The plan was to put them on some D-specs once teh AGX's died....but they haven't died yet.) They feel significantly better with upgraded sway bars, strut bars and control bushings...but then, what doesn't.
LOL if you register, log in, and say 'hi' there's actually something there. If you think they're a bunch of asses, FYI about 75% of the people here are members there. there's about 50x more info there total and AFAIK there's nothing here that isn't covered 3 times there.
