Great info and glad this is a sticky.


Now please specify what 350z set-up I need for my 2005 sedan with non-sport suspension so that I can get an even drop, great OEM ride

 

Wait, doesnt the coupe with 19's have 427 for the rear spring rate?

 

yea..i think ur rite..i changed it..can someone confirm the numbers?

 

They are correct. Though I can tell you that 06 Z's did not change spring rates from 05 car's, no change in springs.

 

nicce.. i got the s techs.. they have great handling but a lil low.. i like ur setup.. looks clean man! another nice sedan drop =) lovin' it

 

thanks man

 

do the sport sedan ratings (314/342) apply to 2006 models also? any way to verify this?

 

Absoltg I do not think they changed the susp from 05-06. I haven't heard/read anywhere that anything was changed.

I had the susp from a 05 350z roadster and stillen sway bars installed this past sat. I love the way my car rides and handles now. This is what I would call a sport suspension. The ride is only minimally harsher(I would say stiffened positively). Car handles a few ticks behind what my wifes s2k does. Absolutely no bouncing over rough/uneven terrain. No floaty feeling when entering/exiting curves. Also something I don't recall anyone saying. Is that the squat(the 6mt exhibits when launching) is gone. Nice solid launch now. Gone is the pogoing that use to be there. Overall I love the new feel and character of my car.

 

i am planning of getting 350z springs and shocks for my 03.5 sedan. I dont have the sport package on my car. What else do i need to make this setup work? and which rear springs and shocks should i be looking for?

 

Great info. I was talking to vrsc about this over the weekend. I have the 05 with the sport suspension so maybe we can do some testing on each. I am definitely intersted in pursuing this mod.

Thanks for the exchange of knowledge.

 

igor, since u dun have sport shocks..i suggest go and buy shocks and springs from an 05 350z...that would be ur cheapest route..

u can post up on my350z..cause i'm sure somone will be selling it, or you can put a wtb..

good luck

 

Please post the spring rate for a 2005 non sport suspesion sedan

 

03-06 G35 sedan non sport suspension spring rates
283/308

 

Every single change they have ever done to the Z, G coupe or sedan Nissan/Infiniti has gone out of their way and tipped us off that a suspension change occured. We knew in advance about the suspension revision for the Z in 04, they told us about the 05 coupe sport suspension getting stiffer springs, shocks and sways*. Nothing has changed on the sedan shock and spring wise from Job one in 03. All 05 sedan's did get stiffer sway bars. (*They likely mirror the 04.5 Z revision where only the car's front bar is stiffer and that was done on the sly. No change in mean bar diameter, but thicker wall's in the bar's hollow construction).

 

gsedan35, thanks i appreciate the insight. now i need to hunt down some '03 or '04 unrevised springs!
