SWAY BAR
I have read many thread on this before but I still don't know which is the best sway bar in performance[IMG]i/expressions/face-icon-small-confused.gif[/IMG][IMG]i/expressions/face-icon-small-confused.gif[/IMG] I want my car to keep flat in the ground[IMG]i/expressions/face-icon-small-smile.gif[/IMG][IMG]i/expressions/face-icon-small-smile.gif[/IMG] I have Ground Control with Konis and Eibach camber kit. Any suggestions on which sway bar to buy[IMG]i/expressions/face-icon-small-confused.gif[/IMG][IMG]i/expressions/face-icon-small-confused.gif[/IMG]
if you want the ultimate performance sway bar, you are gonna want Suspension Technique Sway Bars. They will keep your car flat around turns. Ive read a lot about these RSX-Type S sway bars that we can put on our cars, but if you want to up the antee even a bit more, Suspension Techniques is for you. Thats what i am gonna get on my car. I had my good friend that has all the links to the aftermarket world look into them for our cars. He said that they were starting to put them together for our cars, but it could be up to 6 months before we see them. But if you can wait a bit of time for ultimate performance, you wont be disappointed.

Rep Power: 0 I was told that I can put an RSX sway bar on our cars. Is that true[IMG]i/expressions/face-icon-small-confused.gif[/IMG] If so can we put an aftermarket on since they are bigger and better and they are also already out

Rep Power: 0 dont get the RSX Type-R sway 22 mm from at clubrsx.com, the price is about $85.95 ...because u will make the sway bar ratio off balance...then if u doing hard braking, ur car is more likely to slide....

Rep Power: 419 Why did you come to that conclusion. Here's the conversation I had with you...

That's right, I don't. I don't know if it's hollow either. I'de assume that they use the same material for the 19mm and the 12mm bars on the stock RSX's and Civics though. I also noticed that someone on the ClubSRX.com forums said that after he installed the JDM rear sway bar onto his RSX and there was an improvement. That and the fact that the 19mm rear sway bar seems to be less stiff than what we need tells me to get that 22mm rear sway bar.

thanks...last question, sorry...but how do u know the JDM 22mm sway bar matreial? and the stock EX front sway bar material? i mean if the materials are the same then it's great, but what happened if the materials are different?

We're only taking into consideration the major factors though. Maybe there could be other problems that arise? I can't see any off hand. The car would basically stay flatter and could take turns faster because its center of gravity wouldn't deviate as much from its original location.

Didn't see your replies before I replied... Just read my previous reply. I'll go with the 22mm rear sway bar as well I think after these calculations.

I did some more calculations and I had some discussion with my father and we came to the conclusion that a 22mm sway bar is the way to go.
We checked out the stiffness compared to the weight.
So...
(22/24)^4 gives us the relative stiffness of the 22mm rear sway bar to the 24mm front sway bar. This means that the 22mm sway bar is about 70% as stiff as the 24mm front sway bar.
THe weight distribution is 40% in the rear and 60% in the front. This gives us the ratio of back-to-front weight of 40/60 or 67%. This is almost the same as the stiffness ratio mentioned above. Therefore we have almost the same rear-to-front stiffness ratio as we do the rear-to-front weight ratio.
In comparison, (19/24)^4 gives us the relative stiffness of the 19mm rear sway bar to the 24mm front sway bar. This means that the 19mm sway bar is about 40% as stiff as the 24mm front sway bar.

The only thing that'll happen is that the rear will be anchored more and the rear of the car won't lift up as much off the ground. That is if you brake in a straight line. If you change the stiffness of the rear and the front is still softer, then the back of the car will tend to want to slide out from under you during turns. Maybe if you brake during a turn then this will be more pronounced.
>> sorry 1 more question...do u know the stiffness between the stock EX 12mm sway bar and the Honda JDM type-R 22mm sway bar?
If they're both solid, then the stiffness will increase like so:
(22/12)^4 ~= 11.3 times as stiff as stock
(19/12)^4 ~= 6.3 times as stiff as stock
This is coming from a mechanical engineering book and my father's help. He's a physicist. Whoa! That's seriously stiff. The 19mm bar is already 6 times stiffer than stock, but the 22mm bar is a whopping 11 times stiffer than stock. Hum... I remember someone saying that they consulted a mechanic and he said the 19mm was as much as we'de want to have and stiff be streetable. This also assumes that the bars are solid. They might not be, in which case the stiffness values might change.

hey...Grey..if i upgrade the rear sway bar to 22mm...will that effect the car at all..i talked to my friend he said, if i change to 22mm rear sway bar, and when i do some hard stopping my car will end up sliding, is taht true?

Rep Power: 419 If you meen work as in fit then the RSX sway bar will fit all civics equiped with a rear sway bar. 2001 LX's and DX's will have to weld on little end link attachment points onto the rear lower arms and drill holes for the bushing brackets. If you meen work as in help the car corner properly, then I don't know? Maybe, but it could be a little too much oversteer. Upgrading the front rubber bushings to polyurethane ones might even everything out nicely. That's my plan anyway...

Rep Power: 0 If you already have springs and Koni's, then just what is it that you are going to do that requres even more beef in the suspension? Like, all those big sway bars and stuff are going to be above the capability of the car itself. Kinda like squirrel hunting with a .50 cal rifle.

Rep Power: 419 Nah, each suspension component does a certain thing. Springs dampen the up and down movement. Shocks prevent springs from rebounding. Sway bars prevent chassis sway. Strut bars and tie bars prevent chassis deflection. Everything has a purpose.

Rep Power: 0 Well it ain't going to be much fun riding around daily in a Civic with all that stuff on it unless one is going to compete.
My care already has enough sway bar to handle just fine with the shocks and springs.
If a person is going to go all out, then he should get a real suspension tuner to do the whole thing and match everything to the car and the purpose.

Rep Power: 0 Have any of you guys ever driven an ITR. This is probably the most balanced FWD out there. This is done through bigger sways, stiffer springs and upgraded struts. The best part about it is that the ride is not rough at all, just firm enough to feel in control of the car at all times. When you look at the way our cars handle and compare it to an ITR (RSX R), they handle like poopy. The cars are different, but are built on the same platform, so we have the potential. Personaly, I'm just waiting to find someone who would let me attempt to instal an RSX suspension (springs and struts) in my civic to see if it fits. If so WOPOOOHHHHOOO!
