I'm re-posting this from the other thread:
i've used eibach [PROKIT] on my prelude and did have the opportunity for h&r at the time. in those cars, a lot of my friends with h&r did "bounce" more. but that could also be that h&r tend to be lower.
Eibach was great though in this car I'm going H&R for a more aggressive drop. Eibach [prokit] my handling improved a lot and it felt stock.
Both are good companies. If you want more comfort, the eibach may do that, better handling, h&r.
