They are sporty but not hard as H&R. btw. H&R and Hartge are also the same springs 
They will bring your car down 35mm |
I read that Eibach manufactures ACS springs, but the ACS specification for the steel used, and performance, are not the same as for Eibach. When you say that their "papers" are the same, do the papers contain the specifications for the steel and spring performance? I'd bet that these trade secrets are not available to us, unless you happen to have some friends in very nice places!
