which swaybar you choose is dependant on your driving style. front bar will degrade rear lateral force and a rear bar will degrade the front lateral force. if you want to feel the car on corner entry, front bar is the way to go. if you want to REALLY feel the car rotate through the middle and on corner exit, then rear sway bar. too big of a rear sway bar for your driving style can induce unwanted oversteer.
my personal thoughts are if you can't get into the corner, how are you gonna get off the corner?
