Spring rates

Anyone know the spring rates for the stock springs, H&R Sport, RDSport, and Eibach?

Apparently, this is an unknowable thing.

Should be able to get the eibach rates by calling them. They're local too.

H&R doesn't release their spring rates for some reason. And since they make RDsport springs, I wouldn't expect them to be much different. Typically stiffer than eibach.

If you get the rates from the manufacture, it will most likely be a progressive average.
