I am considering buying some esplir (sp?) springs from a member here. They are for a G35 sedan with a drop of 1.6 inches and increased spring rates by 30%.
I have an 04 coupe. From the research Ive done, it seems as though I could use these to get a 1 inch drop all around and a softer ride.
That is what I am looking for. There are no problems with doing this correct?

Shocks will be new Tokico HPs.

 

They will work.

 

back off they're mine! hahaha

Espelir ASD G35 Sedan drop 1.6"/1.6" linear front/progressive rear
Spring rates 241/347

I know someone has a sale they'd like to make, but as a reminder, your oem 2004 spring rates are 314/342. Having that much less spring in the front AND taking out ride height as in less suspension travel, aren't two things that play well together. You'll be getting to know your bumpstops on a very intimate level.

If your going to get them anyway, I hope your Tokico HP's are 350Z part number specific vs G35 specific. 350Z HP's should have the oem Z shock's shorter body/piston rod lengths.

 

I will have some Eibach Pros available in a couple weeks, if you are interested.

 

In general, springs made for the sedan will lower the coupe ~0.5" less than they would the sedan. So if they drop the sedan 1.5" they would drop the coupe 1".
