'03 Z sway bars work on '04 sedan non-sport?
I am looking to lower my '04 Sedan Non-Sport suspension on 245/35/19 +35 using the stock 350z shock and springs. The non-sport G springs should have rates of 238/308 and the '03-'04 Z should have rates of 314/342.
I hope this will improve performance and look better dropped an inch!
Should I get the '03 sway bars from the Z while I am at it? Will they work? Do I even need new sway bars if I go the route above?

If you want performance, you want to change the struts or tires... springs drop your ride height, but not enough to really make a huge impact on the way the car drives by itself...
I'm not saying you won't feel any difference with the springs, but the advantages to better tires are obvious, while struts are what holds the tires to the road so either of those two will make a bigger difference by themselves.
A rear sway bar and chassis reinforcement will still make a noticable difference too. It just depends on what level of performance you will be satisfied with.

But from what I read, the 350z swaybars aren't any better than the G units (stock for stock) Or no one has actually taken the time to really measure the Z units to G units. So for now, I'll say the stock Z bars will yield nothing over the stock units.

There actually is evidence that the newer Zs and maybe coupes do indeed have higher rated swaybars. You are going to have to do the legwork yourself on this one though.

The only thing I can think of with the sways is that if the spring rates are higher on the 350z, then the 350z sways are probably designed with stiffness to compliment the spring rate.
Your money and time would be better spent getting the Stillen or hotchkis sways to go with your 350z suspension. That will be a worthwhile and noticeable upgrade. Plus they are adjustable so you can set the stiffness to your preference although I think all the settings are stiffer than stock.
I am going to drop on 350z suspension this thursday.
After I get a chance to see how it feels with stock sways I will decide whether or not to go for the Stillen sways. I don't really track the car so if the stock G sways feel good with the stiffer 350z suspension I will just leave them.

Well how could his money be better spent if he already has the Z swaybars. He's best use of his $ and time, would be to research if his are actually upgraded or not.
And I already have the Hotchkis bars on my stock non-sport 03 Sedan w/ coupe 19s. I ran them with the stock 17s also. Very worthwhile mod.
I'm also planning on going Z front/Coupe rear springs w/ Coupe shocks soon. I'm going to run this before dialing in more stiffness on the front bar

Yeah, I was actually referring to this: Since you didn't provide a quote to exactly who you were replying to, perhaps you should come up for air once in awhile also

I got these sways free (threw in for the price) from the owner of the 2005 350z suspension I bought. I figured that these Z sways would make a difference but couldn't find any info to clarify.

Look for the discussion w/ Gsedan35 starting on page 9. https://g35driver.com/forums/showthr...t=55776&page=9

Yeah, I read all 14 pages last night and all I got out of it was that Aftermarket ones are the way to go. It did say the that the newer Z's and G's have upgraded/better sways.

The data that exists is soley on the 350Z as no one has done any footwork on the G35's, but history show's us the G35 has followed the Z in oem bar useage. When a 04.5+ Z front bar was weighed against a pre 04.5+ car, their was a weight differance, yet the bar's outside diameters are the same. We believe that this is do to thicker wall constuction inside it's hollow walls. Current calculation's give this bar about a 20% increase in strength.
So what does this mean. Nothing really, it changes nothing since you are still best served by picking a adjustable sway bar setup that can adjust front and rear. We should not be in the business of trying to pick bars based on percentage of stiffness higher then oem. Sway bars should be used to fine tune a chassis setup that has been dialed in. Use sway bars to fine tune a already well sorted setup, not well sorted you say, make other changes first to get their, then use adjustable sway bars to fine tune.
The only reason to specifically pin down high bar strength's is because you are directly pinned down to SCCA class rules which limit you to changing your front bar only. The highest front bar strength's can be found in the following product order.
CT-1 (run a search on my 350Z.com)
EVO350
Hotchkis
