With Eibachs on my 2003 coupe, that thing was low. Much lower than the sedan is now. Anybody have 350Z front springs that I can try?

 

You should try my350z.com.
I got my set there for $80

 

I currently have 350Z springs installed and looking to replace them with sedan sport suspension springs. Maybe we can work something out...

Thanks

 

I don't think it's worth the money. I have an 05 6MT, and I got the shocks and springs from an 04 coupe 6MT. Yes, there was a drop, but marginal. The only people that would notice are possibly only other G owners, and only if it's parked. The ride quality is the same, and though I haven't really driven too aggressively since their installation, it seems to handle about the same right now.

We wouldn't have spent the money on the shocks/springs by themselves. However, they were included in a set of coupe 18's we got for the wife's car. And we're going to be putting my old stock shocks/springs on hers, as her car did not come equipped with the sports suspension.

 

must be nice to have 2 Gs to share parts

 

Well, the ride in my 05 6mt with the 05 coupe sport springs did change. It is much more planted and does handle better. I like linear springs as well.

 

Well, If you want the OE sedan Sport springs, that is do-able!

 

It's not recommended, Handling will not be good.
You should be able to hook up with some used Z springs & shocks for little cost.

 

I got my Coupe springs for $40 shipped and did the install myself. Like others have noted, I noticed better handling with my G on Coupe springs and Sport struts. I also find the ride to be better.

I've driven a G sedan with the 350Z set up and noticed the ride was choppy, very busy, and the suspension bottoms out on choppy surfaces. The reason I went with the Coupe springs is for the following reasons.

1) The Coupe springs are designed for a car with the same weight and basically the same weight distribution. The 350Z springs/struts are designed for a 200lb lighter car. It does make a difference.

2) Dropping a G sedan 1+" puts the camber out of spec. The front camber is not adjustable and the rear camber is only slightly adjustable. The only way to really put the front camber back into spec the right way is with $300+ camber arms. The 350Z springs make for some serious negative rear camber. Even the Coupe springs introduce more camber though the tires seem like they can handle it. The 350Z springs on the otherhand will require different camber bolts, along with some drilling, to get rear camber close to, but not completely into spec. Running more negative camber can improve lateral G's, but it will hurt straightline stability and on-center feel.

3) The G sedan's suspension geometry wasn't designed for a 1+" drop. Operating the suspension far outside of it's intended design can introduce nasty things like bump steer, snap oversteer, caster issues, dartyness, lack of feel on initial turn-in, etc.

4) The G sedan needs shortened struts to compensate for lost wheel travel. The 350Z struts are shortened, but they're very firm.

5) Though visually pleasing, lowering doesn't automatically mean better handling. Ask any suspension tuner and he'll preach this to you. You can typically lower a suspension .2-.6" and get some good results. Anymore than that and things start to get compromised for the reasons listed above. $3,000 coilover setups are great not because you can drop the car 2.5", but because you can adjust the suspension and tune the ride height and dampening. Most race tuners only do a .5" -.7" drop with coilovers. You don't see them doing 1.0-2.0 drops on true performance cars. Wheel travel means everything. If you really want to improve the handling of the G sedan, get swaybars, 17X8 light weight rims, ultra sticky rubber, and Koni Yellow struts and maybe Coupe springs.

Take a look at how much the factory tuners lower thier cars over the standard models. It's usually .25-.35" along with stiffer springs, firmer struts, wider rims, better rubber, and sometimes different roll bars at one or both ends.

 

Yes, the struts will die a quick death. Even the firmer Sport struts will die quick. The reason is the 350Z springs have a stiffer spring rate. Struts/shocks are dampners and are designed to dampen a particular spring rate. The 350Z springs will basically overwork the struts and kill them quickly. More importantly, the reduced height of the 350Z spring will put the G sedan struts far outside their intended operating range therefore killing the struts even quicker.

There is no way around this. A lowered ride almost always means a stiffer ride. The spring rates and dampening rates have to be higher to keep the car and suspension from bottoming out. Progressive rate springs like Eibachs offer a soft feel initially because their upper coil rates are softer, however when a fairly big bump is encountered, the spring compresses and the higher rate coils come into action and firms up the ride. This offers a decent compromise in real world driving, though most performance drivers prefer the consistent feel of linear rate springs.

 

Definitely I do want them. Email me at crzydmncn@yahoo.com and we can work things out.

Do you want the 350Z springs?

 

Its an even drop all away around, its just the sheet metal on the front wheel wells was cut higher then the rear. I have no idea why they did this, its the same for Altimas. If you look carefully at a stock G35 you will see the back end has the illusion of looking lower also, its just becomes more noticable when you lower the car. Only way to make it look more even is to have springs that drop the front more then the rear.

 

Read post #12 and your question was answered.

Evening out the gaps looks better, but isn't better for handling. Infiniti designed it that way for a reason. If it makes you feel any better, BMW does the same thing.

 

Ah thanks always wondered why they did that... Funny tho its not noticable on coupes, just on sedan cars.. Atleast from what I can tell anyways..
