Koni's are the best bang for hte buck I have them on my del sol and they were a huge improvment over the agx's I ran before and this is with off the shelf valving. If you are serious about autocrossing there is no better shock, as It is a lifetime shock, you can send them in to rebuilt/revalved chagned to doulbe adjustable or shortened, just about anyhting you want from koni.


EDIT - Ok I just relized you were talking about the koni coilovers, have not run them as most people just run koni yellows with ground control sleeves. But I have no doubt they are great, you should call Koni North America and as for Lee Grimes he can help you out.
