you can read my mods in the sig...

but i noticed that if i go into a turn or the twisty's ...i can feel the front end dip and the rear wants to come around. pretty dangerous if you ask me. no Im not trying to push the car past its limits in speed as i enter the turn.....
On/off ramps and pretty hairy!

I think its called over steer? or is it under? LOL i dunno. just seems like im constantly wandering all over the road and the turns just make it worst.


but what can i do to fix this issue?


I thought lowering and Bilsteins would give a better handling?

What sways are on it and what hole are you using on the relo brackets? How many miles on the Bilsteins?

bils and the stranos and not even 6 months old....I dont know the mileage.

Front sway is the stocker that can on the TA....I put the thicker sway that came off my IROC on the rear.

Im using the bottom hole on the relo brackets.

If you added rear sway bar diameter without adding front, the car can increase oversteer tendency. Also with relocation brackets, as you enter a corner, the outside wheelbase increases and inside wheelbase decreases and can contribute to roll oversteer.

A quick test would be to move the LCA's up a hole and see if your tendency improves. Unless you're drag racing you should be good to go in the first hole instead of the lowest.

You could also decrease rear bar size or add front bar size then check the balance.

i dont have a caliper to measure the front sway bar..but it is the thicker one. SO i put the thicker sway that came on my IROC to somewhat match.

my old TA rear sway was way smaller than the front but now they are both about the same size.



You are describing exactly what im feeling....."roll oversteer"

UMI Sales

If you added rear bar to a balanced system the car will tend to oversteer (or understeer less, or whatever). Provided it was balanced to start with. The tendency is toward making the rear rotate more.

Are you drag racing? If not, I'd move 'em up a hole and try it.

Many drivers run relo's on the lowest hole with no oversteer tendency but corner oriented drivers sometimes prefer the higher setting due to that feeling.

No im not drag racing the car.....I will move the LCA's up 1 hole.

so should i put the rear sway that came on the car ....back on it? and take the thicker one off?

UMI Sales

I'd try the relo's up a hole and see if it suits.

If it still oversteers, then you could put the smaller bar back on or add front bar.

Adjusting the relo's would take about 10 minutes and be a good first step.

Let us know how it goes.

will do ....thanks for the info.

Yeah if your not doing drag racing, you typically want the LCA's parallel to the ground, or even angled down from axle toward chassis. Roll understeer tends to keep the car stable around corners.

i thought also...for handling, you want a thicker sway on the rear? if you have a thick on the front.

For handling, you want whatever feels best for you. It's a combo of keeping your tires attached to the ground as much as possible.. being able to control the car in a slide.. etc. So it's really a personal preference thing.

Now that being said.... Here's a few ideal popular setups. 35mm front bar and a 22mm rear bar works very well all around. I've been playing around with a 35mm front and stock 19mm rear. It's worked decently for me, but I may go back to my 22mm rear again. Something a tad softer but well balanced would be the 32mm front and stock 19mm rear.

Those larger 25mm rear bars will limit your roll in the back by quite a bit. The problem is that when it breaks free, it breaks free quick and is harder to control on the edge of traction. Under certain circumstances it could cause more understeer.. other circumstances more oversteer. All in all, you are trying to balance the car so that you minimize both over and understeer. Sometimes its better to let the springs do their job. Sway isn't always a bad thing.

I am purely speaking from an "at the limit" standpoint. Street driving it's pretty tough to put your car at the limit safely. For people who just mod their car for street driving, you can pretty much do what you wish. You're not really trying to get an edge on anyone on the street anyway.

Don't need a mic. Get an adjustable wrench, put on the sway bar in the middle of the car and adjust the wrench so you can just slide the wrench off. Measure the gap. (say 1.25"). Take your measurement and multiply it by 25.4 (mm = 1 inch) (using my 1.25" as an example, 1.25x25.4 = 31.75 or a 32mm sway bar)

If the front bar is just a touch smaller than 1.25", then you have a 30mm sway bar.

I'm following this .... as I have pretty much all the suspension pieces that the OP has. They're all new (under 4 months old). I have the dangerous oversteer problems ... and will take the aforementioned advice of moving the LCAs to the upper hole.

I don't know if I'd use the word "dangerous". It's more like an awareness thing.

my rear sway measures 7/8 of an inch. its the one that came off my IROC.

I never got around to measuring my front yet but its what ever came stock with my TA.

I did move the LCA's to the upper bolt holes.

stroked383HSR

iTrader: (12)

to me its dangerous....I have lost it around a few turns already.....and seen POS's go around the curves about the same as me with my problems.


so something just is not right.

YEP!!!! thats what it feels like

If you have the same size sway bars front and rear it's probably killing the balance. Sounds to me like you should try the stock rear bar again.

if you guys really wanna see the difference take the rear bar off completely and see if that fixes the problem. Should make it want to push the nose like a dumptruck in a hairpin
