bullitt suspension( with or without the bullitt sway bars?)

i am going with the bullitt suspension. now i can get the springs and the shocks and struts.......or i can get the whole suspension with the front and rear sway bars.

heres the question, are the bullitt front and rear bars worth it. do they really help cornering ability or stability? dont the gt already have a front sway bar?

one more, i ask worth it, but not about price, cause there is not a big price difference between the to kits. i am trying to drop the weight of the car and dont want to add sway bars if they dont help anything and just add weight.

anyone know the weight of the bullitt sway copaired to stock? how about the bullit car itself, does it corner much better then a stock gt? any # on the slalom test?

thanks guys ......
