Struts, Swaybars

I need some advice on this subject.

My friend mechanic came over to my house and mentioned I should get a bar that is under the hood that will allow the wheels to stay on the road and not cause the steering wheel to gitter when accelerating. What is this bar called and how much would it cost? Also, would it be better to get just the bar or also get Stillen Struts or Swaybars?

Speaking of Struts and Swaybars. What's the difference and which would be better to get? Would I only need front struts, rear or both? Or is there something out there that would be better than both.

As far as handling on my car, there is nothing done to it. So I'm looking for any help in this field.

You'd think I was at a strip club, at the amount of money I'm spitting into this car :eek:

Thanks guys

ok, here's the breakdown on the bars.
Front strut bar - holds the front struts together to increase chasis rigidity, in your engine bay.
Rear strut bar - holds the front struts together to increase chasis rigidity, in your trunk.
Rear swaybar - goes underneath the car, reduces bodyroll.
Stillen has all 3 of these available for the 99 G20. let me know if you are interested.

Oh, this is far more exciting and expensive than going to the peelers.

:hehe: You love using that word don't ya George.

But you'll get way more enjoyment out of your G than you would from those beotches at the club. :D

Well, I have to excercise what little knowledge I have of the local slang. :D

Oh yes.

Hmmm......

G?

G-string?

G?

G-string?

No question, even though both can be expensive. ;)

Make mine a G. :D

Yep, if it's got tits or wheels ... it's gonna cost ya one way or another!:p :p

Yep. The trick is determining which is the better ride. :right:

God thinks "Hmmmn ... you may have a point there ...", then goes over to the celestial computer to check a few things.

When he comes back he says, "According to the latest figures, there are still far more men riding my creation than yours"!

here is a post of mine, read up.

Here is another on strut bars

The main thing you want to remeber is front wheel drive cars understeer, so you dont want anything else that could break the front loose. The softer your suspension the more need for thicker sway bars to reduce roll, If you have a sport suspension, the less need for thicker sway bars.

Front wheel drive cars should have a thicker bar in the rear than the front IMO. For RWD cars the opposite since they tend to oversteer.

The reason you want a thicker sway bar when you have a stock or non sport suspension is beacuse the stock suspension does not keep the wheels glued to the road, it is all compression (travel (soft), and little rebound (soft)(a lot of travel) so you need the thicker bars to tranfer the load from one side to another, this is a cheap way for manufacturors to make the car seem more stable, soft suspension=large anti-roll/sway bars. When you have a stiff suspension, the shocks and springs keep the tires planted, which requires less transfer, if anything a thick swaybar will break you loose, in some situations.
Good luck :)

yikes...Stillen's front strut bar wont fit the 2000 models because of the revised intake manifold...it wont clear.

It's not really good to make such a blanket statement. Other suspension factors come into play, as well as the design of the bars. The Sentra SE-R and the P10 G20 (the two SR20 cars I'm most familiar with) would be down right dangerous with a rear bar larger than the front.

Also, RWD cars do not necessarily tend to oversteer. Most actually tend to understeer. Again, suspension and tuning come into play. With RWD you do have the additional factor of power oversteer in some cars.

On an interesting side note, German engineers have a tendency to either not use swaybars or to use relatively small ones. They prefer to use the springs to get the roll stiffness they desire.

Ok let me rephrase it, non-sports cars that are front wheel drive usually those under 25k, compacts, mid-size understeer heavily. I am not talking, 30mm in the rear and 20 in the front, just a subtle difference.

I make this statement because most stock suspensions are soft, and designed that way, so w/o changing out the shocks and springs you can apply more aggresive sway bars to pick up the slack. (The german cars don't go this route) In the US there are few RWD cars that are not oversteer happy, besides the Miata and S2000, mainly because of the suspension/frame and weight distribution.

I would actually prefer using a 12mm bar up front and a 16mm rear for my car. understeer even with a sport suspension is still apparent, not that I want oversteer, it is about the balance,a lot is up to the driver.
How does the car react now?
What don't you like?
Then you can decide what to do.

Sure most autoxers dont use sway bars, but most have very aggressive shock spring combos too.

True. I wouldn't dispute that.

That's mostly true today since there are not a lot of RWD cars in the US today. Back when most cars were RWD, most understeered like a pig. Today, most of the RWD cars are designed with enthusiasts in mind. Those that aren't (full sized boats, also tend to understeer like a pig).

What do you drive? I suspect it's not a Nissan product. I have aftermarket bars on my SE-R and race an SCCA ITS SE-R (both with adjustable rear bars) and the bars are something like 25mm/19mm. The racecar is tending to oversteer with the bar on full soft. Also, as I said, the design of the bar is critical. A bar short moment arms would not need to be as thick as one with longer moment arms to get the same effect (and that is how you make an adjustable bar as well).

Anyway, that was my point. I don't think a sweeping generalizatoin like you made is a good one. It really depends upon the design of the chassis and bars. I'd really hate to have someone think they need a larger rear bar on their G20 than their front bar. That would produce wild and dangerous oversteer.

Actually i got the new catalog of stillen and it says the it is for 99 and 00
and it does say in the stillen web site too, anyone tried to fit on a 00G?

Actually, I need to not make sweeping statements here either. :)

I'm not sure about the P11 G20. It has the beam rear axle and Mike Kojima has found that the beam rear axle has significant toe-in, making very difficult to get the car to rotate.

So, on a P11 a large rear bar may work OK, although I've heard from some engineers (including Ken from N-Tech) that it's hard to get a swaybar to work really well on the beam axle.

Yeah I was going to ask if any one has put a rear sway bar on the beam axle and how was it? Luke?

the stillen rear swaybar does the job pretty good but george is right on it's hard to make a swaybar that works really well. the stillen bar come with brackets on each side so you can put it on to the trailing arm..however, there's no specific place that you are suppose to install it so you kinda have to slide it around to see which position gives you the best result.
when i first got the swaybar, i thought it was a miracle...but after taken it to the track, with or without sway bar didnt really make my time faster...perhaps it was the driver's fault though..hehe
