If anyone has any suggestions, I'm all ears. Preferably with progressive springs and final spring rates somewhere around or a little stiffer than oem sport springs.

Pics w/ suspension descriptions would be very helpful

Thanks

 

You should search, but I think you are looking for either 350z springs all around or z springs front and coupe springs rear (not progressive). Z=1 inch drop, z+coupe= 1 inch front 3/4 inch rear. You will have to upgrade your shocks because the stock non sport shocks will blow quickly. Most go with Tokico d-spec ($500+), but you can get the KYB GR2 for the 350z alot cheaper ($230 on ebay).

For progressive I would look at Tein.

 

cool. thanks for the feed back. are the z springs progressive? btw, my main concern is I don't want a saggy rear b/c I first had my eyes on the eibach pros.

 

No the Z springs are linear. If you are worried about sagging then I would stay away from progressive. Not saying they all will, but there is a greater chance than linear.
