I the new owner of an 03 sedan. I ordered a set of revised 350z springs right away to fix the pickup truck look of my car.
I installed them last weekend and I am pretty dissapointed in the results.

The back lowered 1" as expected, and it looks good, I am sitting with about a 2 finger gap over stock 17's.

The front maybe lowered .5" and I have a 4 finger gap. I could be crazy, but my car seems higher than some stock cars I see driving around and I am wondering if there may be something wrong, or if I got the wrong springs.
I was very careful to get them lined up in the perches correctly, I dont think it was an install issue.

The color code on the front was 1 white, 1 green. I googled it and couldnt find what year they were from (I got the springs off ebay).

Here is a picture after the installation. I have about 60 miles on them in this pic and I dont think it will settle any more.

thanks for any suggestions

 

I Think you put the springs on backwards

Revised gives you an inch in the front and half and inch in the back.

Check post 144+. For dot colors

 

you really cant get them backwards - the rear springs are much wider, plus the rear had the 2 red/1 purple dot that is known to be the revised z spring..
and the fronts have the plastic coating on the bottom where it touches the strut I am wondering if I got coupe fronts instead of Z..

here is a comparison of my front spring vs the "Z" spring I purchased
not much height differance next to eachother either

Unfortunately - it seems that you may have purchased the left overs from a Z/G drop but in reverse. (Z rears and G fronts) Hope you can work something out with the seller.

 

I bought some revised Z springs for my sedan. I did a lot of research before buying these over the Eibach springs for the G-sedan. I thought the revised springs give a 1" drop all around on the sedan.

Sometimes the static length of the spring doesn't determine the ride height.

I can double check when I get home because I have the left-overs from my spring swap.

 

I am sorry you must of missed the part that the Revised Springs are the same height as the G/Z setup. aka 1inch in the front and 0.5 inch in the back.

The Unrevised Z springs drop the car 1 inch in all 4 corners.

Measure the top of the wheel arch to the ground. It should be like 27.5 which is stock height. My rear is 27.0 and front is 26.5

if you are at 27.5 in the front then those are stock springs then.

What color were the dots on the rears?

 

That is how revised Z looks like dot wise

The fronts are 1 pink dot/white dot and 1 orange dot, and the rears are 2 red dots and either a purple or blue dot. The Purple gets washed out a bit with the flash.

If your springs look any different then you do not have revised Z springs

 

mine are the same as above:

 

What shocks are you using?


I measured a 1.1" and 1.0" drop and I measured from hub to fender, so we cannot really compare our numbers.

Not that it woudl matter, but I am using Bilstein shocks with a shorter piston length to match the Z applications. The bumpstops that is included on the Bilsteins are definitely shorter as well.


Very happy with my application. I can feel the rear tighten up compared to my sedan sport suspension. Glad I didn't go Eibach because that would be too stiff.

 

^ Measure from fender to the ground. So we can have some sort of common measurement. As I am pretty sure stock height is 27.5

I am on OEM Sport shocks.

Maybe your shorter shocks are making them compress more then stock shocks.

 

This is odd for me since I have an full revised suspension and I have 26.75 in the rear and 27.25 in the front?

 

^ Thats very odd

you have heavy stuff in the trunk? Dont know if that would raise the front up.

 

I don't think anything that heavy would raise up the front. And I don't have anything in the trunk other than the full sized spare.

 

^ I am no suspension expert so I am not sure why your front is higher then the rear. The fronts have been the same spring from revised or unrevised. The Rears were changed to a different spring rate and were a tad taller.

but there is a green dot, which makes everything weird. since its not listed in that thread.
