I know a guy who has these, and he claims they are the best he's tried, as far as a full coilover setup. They should be great for track use/autocross, but the ride is supposodly jarringly hard (sacrifice). I've been in his car a couple times, and could swear you could feel anything on the road, but bodyroll was pretty much non-existent (with only a stock front swaybar). I'd say if you are going to keep the heighth low, go for a full alignment kit, other than that...if you buy them post a review on this thread. GL
