Swaybar setup for s14 with front sway only..grip not drift

[s13pignose]

Okay if you had a s14 with bone stock suspension(front sway bar only), open diff, and were happy with f/r ratio but looking for an upgrade (for less roll) with similar ratio...what would you get with that in mind for grip only.

Are these a bad idea (http://www.zilvia.net/f/showthread.php?t=119775&highlight=godspeed) ....f/r ratio seems more oversteer biased than what I am with just stock front sway bar only. Also would like to be able to choose the endlinks seperate, so thats a factor too. So I guess the bars would have to able to use stock endlinks, just to have that option of choosing.

Thanks

I'd get swaybars all around if you want grip. Not having one in the rear is going to cause more oversteer, especially if you upgrade the front bar without adding a rear. Whiteline and Largus bars are both adjustable, where as Suspension techniques and a few others are not. I personally run the Whitelines and love them...

Hmm how much does adjustability help. Or how much of a plus is it. Also when I think about it not having a rear sway I thought would equal less oversteer. But now that you mention it, if sways help you to keep or increas contact patch, then me having only the front one would mean more grip in the front and less in the rear lol. Which way is it.

Thanks for response

Adjustability helps a lot because you can compensate for different tire setups or road conditions or because you like your car to handle a certain way depending on what track you're driving on etc etc.

Well, adding a rear swaybar will help with contact patch up to a point. Once you start adding more and more roll stiffness in the rear compared to the front, you'll start to get oversteer.

It's like a spectrum... too much rear sway = oversteer... then less rear sway is more contact patch = less oversteer... then too much rear stiffness = more oversteer.

P.S. Whiteline adjustable swaybars FTW

So the whitelines pretty neutral, and with the adjustability I can probably tailor it to like how my car is now, but with less roll?

Thanks migs and JR

I run Tanabe F&R bars and I think they are very good. They are light weight because they are hollow and pretty big. 30.5mm in the front and 27mm in the rear.

[s13pignose]

What type of wheels and tires you running though? I'm still on stock 15's with 195's until I can do better. Does the rear come out easily, cause thats something I definitely don't want. Like I said I'm into grip not slide. Thanks for the suggestion btw. The godspeed ones seem to be similar insize, I'm just afraid if the rear is gonna slide at the slightest turn under throttle.

You don't know what you're talking about. Having only a front swaybar causes more understeer and makes highspeed cornering unpredictable and not fun.

Adding a swaybar in the rear will make the car stiffer in the rear, thus, making oversteer occur more easily. Removing the sway bar in the front and having a swaybar in the rear makes the car oversteer more easily. Having swaybars front and rear that are a good match for you're spring rates (depending on the application) will make the car more controllable, predictable, and "neutral".

Hmmm lets see...stance is 8/6k right? What about with something like them. Looking for coilovers suited for spirited driving and grip, but my car is also a daily so nothing to extreme. BTW any new coilovers coming out to be on the lookout for, also who sells origin coilovers?

You should ask the manufacturer/vendor what is the intention of their particular sway bar setup. Companies like Largus or Swift design the sway bars for higher speed drifts, where companies like Suspension Techniques or Eibach design them to make the car more "neutral". Every company has a different stand point, and its hard to find the right person to get the right answer (most people wont even know).

Nissan intended to design the car to exhibit some sort of understeer so that the normal/average joe wont lose control during turns or when it rains. With this reasoning, they either left out the rear swaybar, or put in a mild one. The result is that the rear wheels don't "follow" the fronts (which has a swaybar). Its all about the ratio of grip in the front versus the rear.

Therefore, as SNCS14 said, adding a rear swaybar will increase oversteer (a larger diameter means more oversteer, a smaller diameter means less oversteer). But matched with the understeer caused by the front, you will get closer to a neutral feeling.

However, diameter is key. If you get too large of a diameter (which goes beyond your suspension setup/driving habit) then you will get oversteer. Dialing in the swaybars is even more difficult when you want to get a pair (which is why its important to ask the manufacturer).

Finally, keep in mind that swaybars is the LAST thing to get when dialing in your suspension. This is the following order:

Wheels and Tires: If you have worn out tires, how do you expect to increase grip?
Suspension: Are you going to lower the car with springs/shocks or coilovers? Has the height/dampening been dialled in? Coilover companies know the faults of cars and design their suspension to fix these flaws. Reduce oversteer for FR/MR Cars or reduce excessive nose dive on FF Cars. Keep in mind your alignment can also be adjusted to suit your driving style.
Swaybars: After everything else, then swaybars are used to change the RATIO of front to rear grip.

This is really a shorthand version of everything, and I probably missed a step somewhere, but this is the same techniques used by most motorsport teams.

Yeah I see your point, think I will wait...thanks everyone for the advice

[redsuns3838]

I would just go with whitelines. screw waiting.
swaybars are probably one of the better suspension upgrades you can do.
