Eibach Prokit
 

There is a guy selling the prokit locally here NIB for $150. I am tempted to pick them up at that price but I have one concern. Are the springs the same for the 350, 370, and G's? He is advertising that they will fit all of them. I just emailed him to find out if he has multiple sets or if he thinks they fit all. Any input would be appreciated.

They will "fit".. but for each application.. 370Z (inc roadster), 370Z Nismo, G35 Coupe, G37 Coupe, G35 Sedan, etc they have different overall drops and spring rates.

You need to find out what the part number is, it's stamped on the spring (if it's not, chances are it's not an Eibach), and then you'll know what it is.

You do run the risk of having too little or too much drop if it's not for your application, and the spring rates change as well. A lot of ??'s go into this.

Thanks For the reply. I just got the part number for my car off of eibach's website so we will see if they match. if not exact then i'll pass.

They do fit but different part #s reason for the Gs are heavier vehicles so the drop will possibly not drop on a Z as much as a infinity different rate. Was searchin myself aswell found some deals just concern of drop
