Sway Bars, Track and AutoX?

synolimit

Find it hard to believe you only changed a whiteline set to full stiff out for a hotchkis, then tested without any changes in suspension, tire pressure, the days where same air temps and track temps (which would have no bearing at all on lap times haha), plus no way you could ever improve with more seat time from track day to track day. Cause that never happens.

Dont know if you're posting for the sake of proper info in this thread, or just trying to intentionally piss me off. But ill try to keep this tread on the path of information.

i have tried several front bars in a day, with the right tools i can change a front bar under 20min. There were times also that it was a completely different day and not the EXACT same track/weather conditions, but im not a noob and have taken such factors into account before i formulated opinions about such setups. Obviously you like nit picking to try and make me look like a idiot, and maybe one day we can torsion test all the 370z sway bars out there to see which one truely is the stiffest. But that of course will never happen, hell i may never even meet you in person. Fact of the matter is my on track testing, research, and experience superceeds you forum opinion in my book, and if you really disagree with me, then so be it. I was just trying to share a little info on a topic i have experience, even though i really dont have to. But call me a sucker i like to share info to a extent (passed a certain point i charge for chassis setup advice )

So if you feel my findings are flawed, then prove me wrong, or just stick to your opinion and potentially have a slower car around a track. whatever floats your boat.

Gentlemen, to those who posted useful info thank you, it's appreciated.

I think I'm going to try a Hotchkis front bar, and probably the White Line rear bar, then it will be time to get some skid pad testing done.

Thanks again.

PS. No reason to try to split c$nt hairs on this stuff, these are just opinions. Of course some opinions are better then others.

Par for the course with Synolimit. He knows all.

Also, Doran actually did a shootout with a torsion test on most of the common retail bars before making their own. BJ has posted some of that information here somewhere, I remember reading the numbers in lbs/inch for various bars.

(Like Hotchkis front was ~990lbs and their bar they made is like 1600 or something outrageous.)

Back to OPs original question lol, maybe describe to us why you think you need more sway bar up front. The understeer on our cars is pretty bad, the sway does help us out a lot by helping the front end stay flatter and not roll, but the correction to understeer is really a secondary benefit of the sway bar on our car. I will probably get corrected on saying that, but at least in my mind a sway bar's primary function is to kill body roll(which can accentuate/compound understeer or oversteer-in our case it is understeer).


If the roll is what you are trying to cure, my best suggestion is take Clint's advice, it's pretty much the same advice Doran racing gives, and pretty much the same advice every track goer with a 370z I know gives. Stiff as possible front bar and then a soft rear to tune it in at let the car rotate. Stock our car always seem to have the nose pointing to the outside in tough corners, never really makes that good pivot like you see the Evo's doing

No one said I disagree per say, but for the hundredth time your stating opinion and its your opinion which I'll disagree too. Seeing the bars side by side and charts somewhat like homer posted I'll believe hard data. You can be butt hurt all you want, gss138 seems to drop to his knees for you which I'm sure will make you feel better but again I'll believe data vs opinion. You're telling me hotchkis doesn't torsion test like other people! Seems funny don't it? Like every manufacture of a part somehow miraculously adds 20hp across the powerband...

soooo doesnt the chart homor posted show the hotchkis as significantly stiffer then the whiteline? on top of this you run a pretty heavy stagger with a narrow front tire, which is what i use to run too and the front whiteline on full stiff was enough, then i went square sizes and it really exposed the front Whiteline as too soft partnered with the KW V3 off the shelf rates. Speaking to Doran, they ran the Hotchkis before they made there own bars because it was the stiffest, they said it themselves.

in regards to GSS138 backing me up, for one he knows me from being in the same socal track scene, he backed up up cause he knows that im not some forum know it all who just talks outta his ***, im actually out there tracking and testing, using my knowledge base of suspension tuning from years of being on track...UNLIKE yourself who drives in the mountains...

Syno you need to realize when people are trying to help you and stop acting like a whiney little child.

For your information, Clint is a very well respected driver on the west coast. He is probably one of the top 3-if not best 370z drivers on the track scene on the west coast. The only people I could say are even in his class are the guy from AE performance, Mike B, and soon to be Martin82. Clint is the test driver for the MOTOIQ project 370z and has been very influential on how a lot of other drivers have built and tuned their 370z out here-and we have a lot of very good fast drivers. Clint is a professional test driver with 10-15+? years of driving and racing experience. He owns, builds, consults on professional/hobbyist race cars. If you like, you can watch dozens of his driving videos on Youtube and you will take 5 seconds off your lap times by following his lines.

You on the other hand, drive hills and entrance ramps in Ohio so you can hear your tires chirp and feel cool in front of your mom/GF/BF/Dog/Goat.

No one is going to take anything you say seriously. Vs. Clint's opinion which is respected by professional drivers and guys that build fast cars.

What it comes down to, is that yes people pay Clint for his opinion. Yet he's nice enough to come to this forum and give some general information for free, and you can't do any better than act like a little penis and asking him where he gets his data. He gets it on the track.

Yes yes yes, that experience and reputation is great and all, but does he weld, bro?

Does he have the balls to permanently modify a leased car?

If the answer to either question is "no", then his opinion doesn't count.

Duh.

I can JB weld, and my car does have a roll bar but I didn't lease it....NO BALLS!!!! LOL

ZMan8

So I was considering getting Eibach F & R and putting front on full stiff and rear on soft. My car is a street car, that will probably see some autoX. Would you say I should get Hotchkis Front instead then?

I looked at Whitelines but got mixed reviews from other members.

WELD ON ROLL BAR to be correct!

Sh0velMan

Bolt on is better.

Unless you have hard data to prove my spurious statement incorrect, I'm right and you're wrong.
