Eibachs are a progressive rate spring:

FR 143- 222 lbs/in
RR 291 -485 lbs/in

Stock is (I believe from what I can find)

FR 165 lbs/in
RR 370 lbs/in

For the street progressive springs are fine, but for those those that will track their cars I would recommend a linear rate as they are more predictable.
