anybody know the spring rate on the eibach pro kit?

check out, or try www.maximummotorsports.com They sell them, and they may even have a chart on their website. If not, just call.......I'm sure they know.

Here's a chart I found. Can't vouch for the accuracy (hope this posts with the right spacing).
