I also want to know if anyone has heard of tokiko springs. I was told by a member that he has 350z tokiko springs and claimed that they drop the sedans about 1.8in in the rear. I have Eibach pro kit rears and I want an Eibach Sportline equivalent drop. I saw on the 350z forum that these spirngs drop the rear (of the 350zs) 1.5in. Will these tokiko springs be too much or just about right??
