genreally h&r's are stiffer than eibach, but to give you an accurate opinion I'd have to first try a car with sportlines. I'm really happy with my h&r's right now. The lower center of gravity allows me to fly through on ramps and off ramps and turns. The handling however isn't much better yet b/c I still have my stock shocks on. However, before I bought my springs I had a chance to try a teg with h&r's sports and koni yellows set on the stiffest setting and the handling was mind blowing...truly unbelievable, and definitely better than a prokit/koni yellow combo or a neuspeed sport tokico combo or whatever. :thumbup: :thumbup:
