I have a set of GCs with KYB AGX shocks. The rear springs are very stiff relative to the front. Everyone says to get the rear ITR sway bar. My car is already a little loose in the rear due to the pring rate. BTW, I bought the "standard kit" from them. The front somewhat soft but the rear too hard. I was a little dissapointed at the rough ride. I will most likely add some tender springs in the rear to soften it up a bit. I do have plolyurethane bushings and a camber kit(FYI).

I was thinking of getting a set of suspension techniques sway bars... they seem pretty much the stock size with mor rigity than stock.

The way I think of a sway bar.....When you turn (let's say) to the left. The right side of the car drops and seperates the control arm from the chassis. The sway bar counter acts this by pulling down on the right Control Arm to bring it back to level. So isn't a sway bar just another way of progressive springs?? Maybe I am wrong. So with my really stiff springs in the rear. A really heavy sway bar seems overkill and oversteer.

Suggestions based on my setup??

 

think of a sway bar as a spring that links your front left/right suspension and rear left/right together in pairs.

since you say your car is already a bit rotation happy, then i would advise against picking up a rear sway only, but then again, i've always leaned towards setting up suspension for higher speeds. It will only make your car rotate more, but apparently that's the fad these days because it handles pretty well at low speeds (i.e. daily driving and auto-x), but once your speeds get up there (i.e. road course racing), it's pretty damn hard to control.

So I guess my point is, set it up for whatever you're going to use it for, but be aware of the limitations. For road racing, you don't want too much oversteer, but for auto-x you want alot.
