Cutting down on oversteer

Looking at buying the Illumina kit, but I'm wanting to know what else should I get i.e. rstb or rsb to cut down on over steer, if at all possible? I currently have a Stillen fstb and I've noticed since installing it the a$$ end feels a little less stable then the front. Any suggestions?

front sway bar maybe? i dunno, my Maxima seems to be understeer happy no matter what I do to it. i wouldn't think just adding a front strut bar would make the rear end unstable; tried messing with the rear tire pressure any?

You can read my list of mods in my sig, and I still battle understeer at autocross. My next suspension additions will be camber plates and BlehmCo stage II LTB. I'm also seriously concidering purchasing a second rear beam assembly and getting the toe belt out of it. What's your secret on getting oversteer?

Nobody makes an aftermarket FSB for our cars, best you can do is Moog end links and Poly sway bar bushings. If you own a GLE/GXE you could swap in the larger SE front sway bar. 22mm versus 23mm but I don't think the hassle is worth the gain. Can it even be done without removing the steering rack?

Maybe I'm getting them mixed up but I thought oversteer is when your rear end rolls out and forces your front too far into the corner. Doesn't it have more to do with rear suspension than front? Well whatever it is, hitting the curves isn't fun when that's happening.

Oversteer accures when the rear swings out while turning, which is helpful at autocross and on the track. But not too much fun for day to day driving.

Understeer in the inability of the front tires to hook up in a turn causing the vehicle to go straight when turning, much like driving on ice.

Understeer - The car doesn't turn enough, you crash into a trea, and you die.

Oversteer - The car turns too much, you spin, crash into a tree, and you die.

Oversteer > Understeer, because you don't see the tree that kills you

If you have Tokico Illuminas, you should be able to adjust the firmness on the struts, try turning the fronts up a notch or two.

I suggest a stillen rear sway bar and lower front tie bar, urethane front sway bar bushings. Got my car pretty straightened out. Was understeering like hell before.

do rear sway bars help much since it is a straight axle?

:

Well I'm going to do suspension on my next paycheck and wanted to get lined out what I should do. Stock suspension isn't cutting it. Just wanted to make sure the mods I do are worth the ca$h. I'm not rich so I can't afford three sets of suspension like some guys can. So I think the list is this:
Illuminas the kit with springs, not trying to go low
LTB I or II
RSB
RSTB
FSTB (already on)
ES bushings
SFC's (maybe, still researching)
All this and the car should be dialed nicely for handling, am I right?
