i've searched and it seems like no one has these springs on their Z. Does anyone have pics of it installed?? It says it lowers 30mm front and 20mm rear but the shop that i bought it from says it will be more like a 2.25in drop. Should i keep these or get Eibach sportlines???

On the U.S. importer's web site it lists the drop spec as 30mm/20mm. BUT, it doesn't show the spring rate. Which worries me since for the G35 sedan application where they do show the spring rate spec, that setup use's absolutely horrible spring rates. Making the following marketing claim, totally false for that application.

"To satisfy the performance driver that wants to extract the best performance out of his vehicle we have developed the ACTIVE GT. This spring empowers a higher spring rate than the ACTIVE SUPER DOWN and has a 30% higher grade stroke volume."

If your dealer is right and they are somehow a 2.25" drop, get rid of them, WAY too much drop on springs and shocks. Might they have the same kind of terrible spring rates like the G35 sedan application, sure hope not simple point of fact is, no one know's either way.
