Spring rates???

[SOHC46]

I was just wondering if anyone here knew how to find the spring rates on the following springs. (99-04 GT Coupe).

1. H&R Super sports.
2. Eibach Sportlines.
3. Steeda.

Before anyone says search... I have spent the last eight hours looking on this site, Mustangboards.com, Modularpowerhouse.com, SVTPerformance.com, and the above mentioned web sites. Thanks for all your help.

Jason.
