Eibach to produce Nismo Pro-Kit springs.

tjlazer · 09-10-2010, 08:10 PM

What kind of drop and what are the spring rates?

Imperial · 09-10-2010, 08:13 PM

1" front and 0.5" rear, progressive... I like how it evens out the ride height front to back.

I know that stock the front looks higher than the rear so this was a good idea for Eibach. I wonder how the original Eibachs faired with the Nismo struts... I guess it didn't look right...

Here it is after installation... picture was taken at the SoCal Centrally Located Meet by Waizzz... and for those that will surely end up wondering... no they will not "settle" any lower than what you see... good springs installed properly will not settle.

Very Nice! I installed factory nismo suspension on my touring model and was not happy how high the front was so this is great. How is the stiffness compared to the nismo springs? Any Spring rate specs out yet or if it's under wraps stiffer or softer?

It's noticeably softer than the stock Nismo suspension over your washboard type road surfaces. I will get back to you guys with the spring rates after I get the production model installed in a few weeks. It seems to me like cabin noise has also gone down a bit with these new springs which is always a plus. And as an FYI, you can have these installed without additional hardware and still be within factory alignment specs.

Are you sure it doesn't need an alignment? A 1 inch drop on the front is quite a lot without an alignment.

You have any better pics and up close ones too?

The drop looked good in person, congrats again.

Looks fine. Also, the modest drop in the rear might help the FI catback system clear some bumps.

They design their springs while taking into account the car's entire suspension system which includes the struts and sway bars so being that both are different on the Nismo from the regular Z, it was expected that they had to create new springs for it from scratch not just to look right but to ride well also.
