I don't work for Stillen, nor do I sell their swaybars so I'm at a loss as to what exactly you're talking about
My location is to the left, as is my company name (as well as in my signature, as well as it being my screen name - I guess you missed that).
My apologies.
I thought you were Adam from Stillen. I did notice your signature and wondered if Adam was moonlighting on a side business! Your response was dead on to what I thought his (Stillen's) response would be, so I'm hoping you understand my confusion. I know he browses these forums, so the comments are still appropriate.
Based on my experience and what I've read on Stillen Sway bars failing, I would still caution others about buying Stillen Bars over the other name-brand suspension component manufacturers.
Installed October, 2005. Started making noise which I thought were the suspension arm bushings last fall or earlier (2009). Lots of noise a couple of weeks ago, and a few week-ends ago, I heard a big noise (sound of it snapping?)
Removed on the W/E (46,000 miles on the sway bars). Looks like it started as a crack last fall since part of the break is starting to rust. Finally let go last W/E.
I’ve never tracked the car, and though I’m an enthusiastic driver, am not overly aggressive. The bars are set on ‘medium’.
Stillen says that their bars are only warranted for 1 year so it’s not covered! I’m pretty disappointed with their response. I probably should have gone with Eibach which Stillen warranties for 1 million miles.
Looks like they have more faith in other manufacturers than their own!
They claim that it must have been caused by hitting potholes or something, but I'm always very careful, and have only had one minor wheel alignment as a maintenance item done since I bought the car even though the car has always tracked true. Anything that would cause the sway bar to break like that would likely have been very noticeable at the time, and would have affected other things in the front end. I believe it was a manufacturing flaw and one of my engineer friends agrees.
Another thread here on My350 about a broken Stillen Rear bar:
Adam at Stillen offered a replacement front bar for a reduced price, but I've lost faith in Stillen. Why throw good money after bad? I asked if they would offer a discount on one of the other brands they sell that carry a better warranty, but they said it only applies to the Stillen! In fact, the price they quoted the dealer to replace my bar with the Eibach bar was a few dollars higher than the sale price per their site!
This has left a bad taste in my mouth for Stillen and I'd have to recommend avoiding some of their products in the future. Sorry Adam, I know you browse these forums, but Stillen's response in this case sucks!
That sucks, has anything like this happened w/ the Hotchkis sways? Wondering because that's what I have and set on the same med settings. Guess that's why the solid bars are the best.
I purchased BC racing coil overs earlier this year and installed them.
Before I go any further I want to say that i now have 115,000 on my 05 350z so the suspension was really worn.
I have purchased tokico blues that blew out in 2 months and then tokico adjustables that all blew out in less than 2 weeks....Tokico would not warranty anything because i installed them myself....I have had a lot of downtime because i need to save money every-time i buy parts....I will never buy tokico ever again.
First up was larger wheels and tires 245's up front and 275's in back 19" and cobb swaybars at the same time.....Following the swaybar directions i went 3rd hole up front (second to hardest setting) and softest setting in the rear.....it felt weird so i put the rear bar in the middle setting because the rear felt jiggly and it has firmed up with the new setting......hence lots of playing with the sway bar settings except i overlooked a few.....thinking it was the coilover shock adjustments i fooled around with hard and soft settings per recommendations of the forums to no avail.....I gave up for 6 months i believe.....I have done nothing since then except say "screw it" and set the shocks to full hard.....made a difference but the front of the car still handled sloppy ( ongoing problem for almost 2 years )...Finally today i decided to do more research but on staggered setups with swaybars....
so this time i tried 4th hole in the front sway bar ( stiffest ) and left the rear in the middle hole...... well whaddaya know.....
THE INSTRUCTIONS ONLY TELL YOU HOW TO INITIALLY SET THE SWAYBARS WITH STOCK WHEELS AND TIRES!!!!!!!!!!!!!!!!!!!
If you have a staggered setup and want a reference point as to STOCK FEEL you really should run stiffest up front and middle hole in the rear to START!
Then go ahead an make your adjustments.
I still don't have the money to install my full whiteline bushing kit and i plan on doing so with my next tax return.
I feel like a sucker.......and i was at the point of selling the car.....looks like I'm keeping it now.....
this was asked earlier, but no one seemed to answer it and seeing as how this is a sticky, I thought this info would be posted as well in the initial thread as a comparison.
Anywho, does anyone know the sizes of the OEM sways for each trim level?

Found this:
Group A
03-04 350Z all trim levels (car's without the revised suspension ONLY)
03-06 G35 coupe (all USDM production with oem 17 and 18" wheels)
03-04 G35 sedan (sport and non sport suspension's
All group A car's have the following oem sway bar specs
34mm front 21mm rear
hollow wall construction 5mm in thickness (courtesy of tomsn16)
Torsional rigidity Front: 1130lbs Rear:385 (courtesy BJ EVO350)
Group B
04.5-06 350Z all trim levels (car's with the revised suspension)
05-06 G35 coupe (all USDM production with oem 19" wheels)
04-06 G35 sedan (sport and non sport suspensions)
34mm front 21mm rear
hollow wall construction 7mm front (courtesty tomsn16) 5mm rear
net change in front bar strength from 2mm increase in wall thickness
+17% (courtesty of tomsn16)
As far as I know 07-08s didn't change.
The Nismo is different..think front is bigger and rear a tad softer than 04.5 set up.
The Front is now 35MM Tubular, not 33MM solid. However, it's now bigger at 35MM with a 6.35mm wall and 3 settings. They actually provided wall thickness! The stock 04.5 up is 34mm with 7mm wall. That puts the Progress around 7% stiffer at the LOWEST setting. It could be a lot more, depending on end tab design and location. I just assumed all other things being equal.
Here is link to FRONT:
As far as rear bar goes, I assume it's also tubular, but they don't say so. It's still 22MM. However, instead of giving wall thickness, they give actual stiffness at each setting! Stock is 380lbs on the rear. Wish they did that with front.
Called Tanabe and they provided me with specs...I already had their rear bar.
The FRONTS are 36MM D with a 5MM wall. That makes them only 4% stiffer than 04.5+ Front bars (34MMD and 7MM wall). There are NO adjustments. Now, it might be that the location of the end links are different, but I assumed same location. They say they are *CHROMOLY* instead of regular steel for added strength, but I don't think chromoly is any STIFFER than regular steel.
The rears are 22MM with 5mm wall, so they are 19% stiffer than stock rears at 21MM and same wall thickness (5MM) which is the same for ALL years.
Now..GODSPEED BARS appear to be a knock off of Tanabe...so look for those to be the same as well.

reviewing an old thread. But I wanted to discuss the numbers from Hotchkis Sway bar.
Bar Rates:
350Z & 03- 05 G35 Front
Hole 1 = 1525 lbs/in (22% Stiffer than stock)
Hole 2 = 1845 lbs/in (48% Stiffer than stock)
Hole 3 = 2270 lbs/in (82% Stiffer than stock)
Hole 4 = 2855 lbs/in (129% Stiffer than stock)
06 G35 Front
Hole 1 = 1525 lbs/in (5% Softer than stock)
Hole 2 = 1845 lbs/in (15% Stiffer than stock)
Hole 3 = 2270 lbs/in (42% Stiffer than stock)
Hole 4 = 2855 lbs/in (78% Stiffer than stock)
Rear:
Hole 1 = 520 lbs/in (80% Stiffer than stock)
Hole 2 = 655 lbs/in (125% Stiffer than stock)
Hole 3 = 840 lbs/in (185% Stiffer than stock)
If I am driving a 05 350z 35th anniversery edition do I use the '06 G35 Front' numbers?
is my sway bar the same as an 06 G35?
From this thread, it seems like the 03-04 350z front sway was softer than the 05+?
So basically... which numbers do I use for the front sway bar + %increase..?
22/48/82/129 OR 5/15/42/78 ?
Just start with hole 2 front and hole 1 rear, then change setting as required to dial understeer/oversteer in or out. The stiffer you go, the less traction that axle has.

Thanks you! Can you explain why the stiffer, the less traction?
Sway bars for the Nismo Z, or other suspension recommendations?
Hey guys! I read the whole sway bar database but it seemed outdated because majority of the post were a few years old. So I have a Nismo Z and everything is pretty much stock. I don't plan on lowering it because I don't won't mess up the incredible handling it already comes with. Well I could but I read to get the same handling that it already comes with in coilovers it would probably cost like $2500+. So I plan to do some light track days (I've never tracked before) but really want to get into it. I had 2006 350z base before the Nismo, and I ordered a JWT Clutch/Flywheel from ConceptZPerformance. However I recently got the Nismo, and the clutch seems to have a lot of life left. So I plan to return the JWT combo, well exchange for something else. Long story short I have $775 to spend, I really want to focus on getting the best possible suspension for track days. Any recommendations? I was thinking the Hotchkiss Sway bar set since its adjustable, but I would love some input!
Looking at post #1 the only updates that need to be done are adding Motordyne and Godspeed to the mix. There has no real updates in sway bars in years, just adding a couple to the market. The Motordyne bar is great , the Godspeed one I would never buy
i dont think i ever saw anything about suspension techniqes. Does anyone have info or experience with them?
ST were THE sway bars to get way back in the day (when S30s were new and dinosaurs roamed the Earth). They had a good rep for quality and effectiveness.
I want to buy Whiteline's complete sway bar set. I have '06 Rev-up with Invidia Gemini exhaust. Will it fit? Any one tred Whiteline? I didn't see anyone mentioning these
I thought that would be a Godspeed sway because of the red exteriror and no company markings at all. As I received the item and measured it. The front one is 23.75mm, and the rear one is about 19.75mm. As I searched, only the whiteline rear sway meets the criteria of 20mm, but this is obviously not that one. The front sway is about 5,5 kg, but the measurement only depends on a home scales with my self on it.
It's OK if you haven't got an opinion about my junk, but please lend me some advice about this: The links on the end of the bars are a little bit out of alignment. Is this a real deal breaker? Is it worth to try to correct them?
