Performance Sway Bars??!!

I noticed the sway bars on my 00 GT seem to be of decent size, so how much of an improvemnet weould aftermarket ones make? How would the make the car handle better? :shrug: So far Ive installed Eibach Sportline Springs, Tokico shocks, Caster/Camber plates, and rear control arms. The cars stays pretty flat in the curves like its on a rail till it starts drifting. But I believe thats the "cheapy" tires on it.
:spot:
 
I have a '00 GT with Tokico Illumina and the Hotchkis TVS which includes C/C plates, swaybars and control arms (plus all the hardware). The sway bars are awesome. I put on everything at once but liked the Hotchkis swaybars (although pricey by themselves--$480) for they allowed me to ditch those stupid quad-shocks that are designed to manage axle wind up. The only thing those things were good for was giving me this "turkey Necking" motion under hard acceleration.

I bet the Eibach kit is decent and cheap.
 
I have $160 invested in my sway bars.

Front = 03-04 Cobra 29mm - $65

Rear = 1998 Cobra 27mm - $89

For a while the rear 27mm sway bars were junk and broke easily but it is now a solid bar rater than hollow. Most people think this is overkill but I like the way it eliminates some understeer.
