Sway bar question, stock suspension...
 
I don't want to give to much info because some people just agree cause it sounds good or sounds like something they heard before. Like in nursing you have to think outside the box when given information and have to know about a few things to be able to answer a question. So ill give key points and I want someone to tell me the effect...??

Stock everything but front sway bar set to hardest setting.

Sadly installed in the air and tightened there too, not compressed.

Front camber- OEM -0.5 to -0.9

Rear camber- OEM -1.2 to -1.7

255 front, 285 rear tires

I don't follow. How did you adjust the stock front sway bar?

That's the only aftermarket item (stock everything but...front sway)

Something crazy is going on and before I say what it is, Im curious to a suspension guru if what I did is like a no brainer.

swaybars should have no effect on your alignment. I have aftermarket front and rear. Alignment is still perfectly fine. Also tightened in the air. Checked for tightness on the ground after 15 miles and again at 300 and again at 1000. Not one loose bolt.

But this isn't nursing. Give us all the info you can so we can help you get an answer. Leaving information out when it comes to cars will get you the wrong answer almost every time. What's the problem?

kenchan 09-18-2013 04:41 PM

yah, unless the swaybar is bent putting preload on the endlinks, shouldn't make any difference.

There's nothing wrong with the alignment, never meant it to be read like that. just giving you the shittie numbers so one person could say...with those crapy numbers, front bars large, this is what will happen driving down the road because...

If I said you get cancer cause its what god intended, a million people would agree with me cause that's what they believe or were told and the thread would be dead. But if I ask "why" to make you think, then we'll get the god comments along with the science comments which is what I'm looking for here.

What's a large front sway do to a stock 370z basically?

You're talking alignment also right? That's not happening I don't believe. I did notice the sway possibly could be installed one way or the other and the ends would be higher or lower at the link. If you lay the bar flat on the ground, the tips of the end will either be up in the air or touching the ground depending which side it lays on.

Do you have adjustable end links on it?

critical 09-18-2013 08:56 PM

i believe having on just a stiff front sway bar will give you understeer. i drove with just the front on before I put my rear in. you definitely need to balance it out.

No. Everything fits and sits nice. Why, what are the thoughts on those?

I haven't taken to many turns yet so I can't comment on understeer but what I have noticed is the car still oversteers with easy except now when it does the tires don't squeal to high heaven. They peel out like I'm on snow. I'm guessing that's more traction which is a good thing.

If not adjusted right. You could preload one side of the car more then the other side.

that's wat i thought too, but i learned early on in my G that the improved posture will help turn-in and overall stability through the turn. but then there is a threshold. :) once you pass that threshold its like riding the bumpstops and understeer is very evident. lol

i run only front aftermarket swaybar on my Z. rear is stock.

Big bar up front, just like the discussion below

Well its sitting even left to right and the bar can sit even when swung up to the end links, zero tension. Personally I'd see no use of an endlink unless I wanted to raise or drop the height of the ends of the bar which would raise or lower where the front of the bar sits. To me I don't see how that'd do anything.

I did install the bar both ways. Once on one side then flipped upside down. The first pic I believe the bar is installed upside down. The ends at the links are very high and the front part of the bar is sitting high also up past the oil pan. The second and third pic the bars flipped. The ends at the links are lower and the front of the bar now sit even with the oil pan.

what size for the front? i'm at 35mm. it felt a little funny with just the front bar on, but i didn't drive for more than a few miles to really get a grasp of it.

mine's a small 27mm on soft setting. (36% stiffer than stock)

that's all the stock suspension needs, imo. my front wheel is 19x9 ET33.
