if i were you marbs, id go with the ford racing drop, then go find a rear sway off a stock SES or buy one from an aftermarket company.
ill bet if you do a stock sway bar with a focus sprot rear stress bar and front lower stress you'd feel a huge difference.
oh, and since you have an 06 like me, most of everything you find wont fit yours. ford changed some stuff in 06. i think the front stuff is different, but the rear is the same. make sure w/e you buy will fit the 06 though. look in the W/T/B/S thread on here for a complete explanation.
and mike at hillbish can get you a good deal on the FR drop. which includes everything(except sway bar) and the springs installed on the struts for the front
