Joe Bullitt here's some info for you taken from a previous post by me
"rsom1 here is the spring rate information you wanted on the Sportlines. Front progressive 456 to 507 lbs and rear 149 to 296 lbs. I got this information directly from Eibach who were very reluctant to share it with me. As for the stock rates, I can't find the link but I think Art Hyde stated them in a q&a that was posted on Stangnet several months ago. (600lbs front 200lbs rear linear) Hope the info helps you out, in any case the Sportlines are great for my purposes."
I have auto-crossed my Bullitt with the Eibachs and they were ideal along with my other suspension tweaks. Additionally I have a good balance of street performance and looks.
