I had both Eibach sport and H&R sport springs, and personally I like H&R better. The ride on both is the same, but H&R looks much better from the outside. Eibach springs seems to be higher in the front wheels.

You can check out this new site, it's pretty cool. Seems to be a comparison shopping for performance car parts and they even have a feature to find parts for your car only.

this could be an awesome source for us if they can get some product reviews.
