i was wondering how makes the biggest sway bar... and the sway bar is just bolt on bolt off right?

 

Why you want the biggest you can get???&nbsp You have any clue on what you're doing?

Anti-sway bars is a real balancing act.&nbsp The combination of your front and rear anti-sway bars has a lot to do with steady-state cornering and whether you oversteer (spin) or understeer (slide off the road).

Help - I just discovered that my inside front tire is nearly off the ground during hard cornering.

Is this why my car understeers?
Will a swaybar upgrade reduce understeer?
If so which one is recomended?

 

i am trying to get most of my bodyroll out in the corners... yes i know what i am doing and am just wondering who makes the biggest and what size is it? thanks

 

rather than getting a giant one, get an adjustable one. Like he said, it's a real balancing act. Too much front anti-roll will make you understeer like a bitch. What other mods do you have to the suspension?

 

i have racing springs.... and i have koni racing struts!! who makes an adjustible one? where can i find info about this.. anyways... sway bars who is the biggest and who makes adjustible

 

sounds like you need more negative camber up front for those corners you are taking. this will allow more of the inside of the "inside" tire contact the road when you're taking a hard corner.

for the oversteer, since you have adjustable shocks you should try making the back stiffer and the front softer. you can also increase the front tire pressure and and lower the back for more oversteer. play with this until you've dialed out the oversteer/understeer and your car handles pretty neutrally. good luck.

 

the inside tire comming off the ground happens with really hard susp.
a bigger rear sway bar will reduce understeer.

 

Go contact ADDCO and tell them you want a 2" thick anti-roll bar...

For a small fee, I can tell you how to get the weight off your inside rear wheel instead:


Okay, for free -- run really stiff springs that aren't long enough to push the wheel down under droop travel.

Contrary to intuition, you want to soften the suspension to make one end stick better. Softer springs = more grip. Softer sway bar = more grip. Softer shocks = more grip. Now keep in mind that this is just for one end of the car, meaning that this is the direction you would go to fix a balance problem. Like if your car oversteers, you can soften the rear springs, shocks, or sway bar to make the rear end stick better and get rid of the oversteer.

I went from 450 to 250 rear springs and disconnected my rear sway bar. The rear end is hooked up big time now and it is fun to drive the car again. I still need to make some changes (understeers badly sometimes -- need softer front springs) but I am enjoying the new-found drivability with the softer setup.

I'm told my FD lifts the RF tire an inch off of the ground coming around Putnam Park Turns 9-10 right-hand sweepers combo. I'd love to see a video of this...cool as hell! I haven't noticed any detrimental effects from this. The only thing someone suggested is that I get stiffer springs...but then I'd probably oversteer out of those turns (like Max says). With the relatively "soft" H&R Sport Spring rates, the grip has been very good through those turns under throttle...thus the right front tire lifts off of the ground, due to the left rear tire absolutely hooked up and taking the car all the way around those right-handsweepers without my FD sliding off course!

 

ok guys.. what about the sway bars

 

Whaaaat...Ted already answered your question....

 

thanks.... sorry

 

 

YIKES!! Your way to sofy and too much roll if your front tire is comin off the ground. You need some stiffer springs bro!

 

I think Ted was being sarcastic ... the Racing Beat bar is about as thick as you could possibly want. Not adjustable though. Call up SpeedSource and see what they reccomend - since they know as much about FC suspensions as anybody (I'm assuming you have an FC).

 

Ryan...sorry...I didn't see any smilies on Ted's replies, so I figured he was serious

 

I little bit of sarcasm and a little bit of truth...

Th original poster obviously has no clue about the real world.&nbsp ADDCO makes custom sway bars to whatever application (and thickness) you want.

The original poster is not happy with the available anti-sway bars already offered for an FC3S (Eibach, Suspension Techniques, Racing Beat), so I said to go bug ADDCO to make them a thicker one if they feel the aftermarket ones were too small...



-Ted

 

hmmmmm

ADDCO.....

maybe make some custom ones for the 20B car......

Ted you got the hookup over there?

 

If that RB bar isn't thick enough for you, then you probably have a 2000 pound stereo ... in which case it's no longer a sports car anyway.

But seriously, sway bars are something you should only mess with if you know what you're doing.

 

I know what's coming...
I actually do, but it's a round about sort of connection.
I came across pics of Chito Solomon's 20B-FC, and he's running a "speedway" bar - splined center with arms.&nbsp Possibly from Tri-Point?&nbsp They are the only folks I know run splined front sway bars...

Either that or keep bugging Paul to hurry up and finish his projects!

i have a question. i got an IS300, trying to improve my suspension and i see some experts here. anywayz, here's my question. i've already have pretty hard TRD sways. and I just ordered some hard damping rate coilovers (adjustable tho). I was wondering if it'll cause a lota under/over steering? what should i do to the damping rate to minimize under/over steering?
so if a softer setup gives more grip, why we need sways and stiff suspension? please help, thanks.

 

Your shocks will only affect under/oversteer during the transitions into and out of corners (like 1-2 seconds worth at entry and exit). During the turns, spring rates and swaybar relative stiffness, front-to-rear, will determine whether you understeer or oversteer (assuming you don't change tires or their pressures).

Theoretically, it's possible overcome the effects of your swaybar rates by varying spring rates, and vice versa. But if you're not talking about changing springs, then the following applies: If your front swaybar is too stiff relative to your rear swaybar, then you get understeer. If the rear swaybar is too stiff, then the car will oversteer.

 

Stiffer is better if you're doing low speed autocrossing where directional transitions are frequent. Stiffer springs/shocks, load the tires more quickly for better response through slaloms and for frequent turning at low speeds (less than 50 mph or so). Drift-drivers also like stiff suspensions, as they can get their cars sliding more easily (especially with hard rubber compound tires like Kumho Ecsta Supra 712s)

Softer is better for "grip-driving" at high speed open track events; the tires load gradually, without shocking the tires and possibly exceeding their grip levels...this is why Max and I say softer is better for high speed grip; we're referring to steady-state cornering stick. At high speed open track events directional transitions are less frequent, and steady state cornering more frequent, and thus more important...
