350z SPRINGS

[yerv[g35]]

hey guys i have a 03 sedan if i swap my springs with 350z springs will it b a direct fit?

thanks guys

[RED_DET]

Yes they are a direct fit. I do not recommend that you use the 350z springs with your shocks if you have a non sport suspension. In that case I recommend just buying a complete *revised* used 350z suspension. Most sell for $200 dollars all day long.

what exactly would you replace then...

springs, struts, control arms,... ???

i need to change out my suspension. change out the back as well?

[RED_DET]

springs and shocks/struts. If you buy a complete z suspension, everything in the front, spring/strut will come assembled. The rear suspension is different, the spring sets separate from the shock.

[tollboothwilley]

should i get the rear spring/struts as well then?

also, which year of 350Z is compatible?

[RED_DET]

There are a few things to keep in mine when buying a 350z suspension. If you want a complete suspension, buy the revised setup. 2004.5 or newer. Reason being the unrevised setup, 2003-2004 had a bouncy effect. The revised setup corrected this problem buy addressing the strut/shock. They also raised the spring rate of the rear shock from 347 to 427, the front spring rate stayed the same.

Now if you have a sport suspension on your sedan already, then all you need to do is change out the springs with unrevised springs, which have a 347 rear spring rate. The unrevised spring is to stiff for the sedan sport shock and it will not be dampened properly.

But in the end, I suspect you probably got 50-60k miles on your current suspension, so a complete z suspension with less than 10k miles from a 05,06,07 Z would be ideal and the cheapest route for a better ride and lower vehicle.

[RED_DET]

Complete, buy front spring/strut and rear spring and shocks. I would look for 06-07 setup which will probably have the least amount of miles.

so last question...

where to find a good price?

[RED_DET]

The magic question... I will shoot you an email.

i have a 03 sedan non sport..and i am planing on buying just the springs off a 04z with 20k miles the guy says he doesnt know if its revised or not...wutcha guys think

[RED_DET]

don't recommend any z spring if you don't have at least the sport tuned suspension already. You will not like the ride and will wear out your shocks prematurely. Your springs are not as stiff as the z springs, therefore your shocks will not dampen them properly. Just buy the complete z suspension that I recommended in previous posts.

thanks alot

I got 350Z S-techs for my coupe (Sport) I think they are 427 rear.. they were the stiffest springs I could find for the coupe.

I'm installing on Saturday, I'll let you guys know how it goes.

[tollboothwilley]

how would the H&R sport springs be with the stock '05 350z struts?

[RED_DET]

You will be fine.

Just beware that H&R sport springs G35 sedan (progressive springs) give a drop f/r 1.3"/1.2" and no spring rate info. H&R refuses to give it out, something that is critical to making a informed buying decision, buyer beware.

With that type of drop you are coming close to needing adjustable suspension components to correct the camber. I have about a 1.2" drop and I'm right at the border on my alignment specs. About a 1" drop gives you some room for error. We all know the adverse affects negative camber and toe mis-alignment.

[tollboothwilley]

cool

guess i'll just go with the stock 350z suspension then

how much does this lower a G?

[RED_DET]

1" all the way around
