I know eibach makes a Pro Kit and Sportline version of their springs. The Sportline are lower and are painted red. The Pro Kit are painted grey...right???
I'm wondering because I know people go back and forth about which is lower eibach or H&R... I'm wondering if the people who think eibach is lower have the Sportline?

 

I think they are the same drop if ya ask me. 1.5 front , 1.7 rear, for both so once settled and broken in they appear nearly identical. I never heard of any kind but the pro kit for the max.

 

Technically I think there are two kinds. The Prokit and the springs that come with the Ground Control coilovers. I think the difference is the spring rates, not sure what else though (beside being able to adjust the ride height).

 

The only Maxima-specific spring from Eibach is the Pro-Kit.

Eibach Race Springs (ERS) are used in the Ground Control coilovers, but they are not vehicle specific. They are only spec'd by spring rate.
