My car has real bad body roll. My suspension setup so far is:
-H&R sport springs
-KYB GR-2 shocks
-Ingalls front camber kit
-15$ rear camber mod
-17" wheels w\weak sidewall tires
I use to have the stock 16s wrapped in some kumho tires, but the negative camber ate them up quick. I didnt get much roll with that setup, but then I got a 4wheel alignment and put the 17s on. front is within specs. Rear is within all specs but is still noticeably negative.

When entering a turn at a high rate of speed. My car first sways because of them weak sidewalls on the tires. Then the body roll occurs and the car leans and feels like a buick. the tires dont lose grip and they dont sqawk either. The grip is there but the feel isnt.

I think maybe a Suspension technique rear swaybar, and MachV lower tie bar, and rear strut tower bar with help this. what do u guys think?

SIDE NOTE: Talon Esi doest come with a factory rear sway bar, so I know i will have to get some GST rear lower control arms, links, bushings and bolts.

getting dual STB's will help ALOT regardless of what some say. in addition to these you can also get the lower sway bars for even more added stability but tower bars would a good first step in the right direction.

Yeah, get a set of front and rear sway bars. Get some stiffer springs too, I believe H&R has 'race' springs available with a stiffer spring rate.

If you upgrade to stiffer springs, it's also highly recommended you upgrade the shocks as well to keep the car well controlled. Adjustable shocks such as Tokico Illuminas and Koni Yellows are well worth it.

Strut tower bars will also stiffen the chassis a little bit... but the first and most important mod you can do to lessen body roll are springs and sway bars. IMO.

get stiffer springs and shox, I got skunk2s with AGXs and my car rolls very little, I've watched it on autox vids and it doesn't hehe ^_^
