Can someone who has the Z/G drop let me know if what I was told by a mechanic is correct. Do I need to replace the struts when I change out the springs? I was told once the struts are removed it is best to replace them or they will leak. Also do I need to have an alignment done?

Thanks in advance!

 

An alignment is necessary, but if you have to wait a few days, you should be ok. I installed mine then drove it 3 miles to get it aligned the same day. You could tear up some tires if you go too long or too far with it out of aligned.
I replaced my springs and the front shocks (with oem ones that less than 12k miles on them). Havent heard of them leaking...

Good luck!

 

Yes on alignment, about 2 weeks after the drop.

uh I will assume you have a Sedan since the G/Z drop is 99.9% done on sedans

If you have the sports sedan you will be ok, if you don't I think the normal shocks will just ware alot faster. If you can find 350z shocks along with the springs your golden.

 

Mostly true -- except if you have sport coupe or revised 350z springs out back (427 spring rate) your sport sedan shocks may not stand up for a long time. I'm still running my sedan shocks/sport coupe springs with no issues but plan to change them out soon for the coupe shocks or maybe aftermarket/adjustable shocks/struts all around.

My front Z springs came on struts so I'm good there, but I think you could use the sport sedan struts up front and be okay. Always best to match, of course, so if you can find shocks/struts that match the springs, you should do so -- OEM ones should be cheap and not too hard to find on the Marketplace (Driver, my350z), Kijiji or Craigs.

 

It's advisable to replace the shocks along with the springs. You need an alignment after the springs have had time to settle, which takes about a month. I put Z shocks on along with my Z springs in Dec. I never got an alignment because I'm waiting for my new wheels and tires in the mail in a month anyway.

 

Ok guess I should have been more specific, it's a 03 Sedan with the sports suspension...up front will be unrevised Z springs the rear springs come from a 03 Coupe...so with this setup if I'm understanding correctly I only need to get a alignment correct? Thanks!

 

That is correct. However whether you change springs or not you may want to replace the struts and shocks just because they are 7 years old. The most recommended seem to be Tokico HP Blue (~$300) or Tokico D-Spec (~$500+). Tokico also made our OEM struts and shocks. Replacing them will give you better ride and handling, but if it doesn't bother you, or you don't want to spend the money, you don't have to.

 

With all this advise this is what I'm going to do... unrevised Z springs on Z Tokico HP Blue struts...03 coupe springs on Tokico shocks and while I'm at it replace the compression rods. What are your thoughts on that set up????

 

Sounds good. Let us know how much you like it when you are finished. I'll be installing Z all around (revised in the rear) and D-specs this month. Coupe springs in the rear would be better, but its a pain to find someone selling just the coupe springs lately. The rear springs are easy to change, so I can always change them out later.

 

theres no such thing as unrevised front springs, the revision was made to the rears only. With your current sport shocks/struts you can do a direct swap of just the springs you got. If you have more than 60K i would recommend replacing your struts/shocks due to age. Get an alignment after a week or two.

Ive been rolling on Z front and 04 coupe rear springs on my stock sport struts/shocks for a year now and have no issues. Im coming up to 60K and probably will be switching to Z shocks/struts and switching my unrevised to revised 350Z rears.

 

I have tokico hp with tein s-techs but I'm too low and I want to swap them to Z/G springs. My question now is if I can use the tokicos with these springs?

 

Yes.

 

I have 350z revised springs and D-specs on my 6mt sedan. It doesn't bother me that much that the rear gap is a bit smaller than the front gap, but with the higher spring rate in back it does have traction problems exiting corners. I think this is the reason that the revised springs only came on cars with wider rear tires. I'll probably switch to unrevised coupe rears at some point. The rear springs are so easy to change anyway.
