I personally thing ST is good. i run a rear sway myself. although 98sr20ve on this board got a bad one for his sentra. it was basically crooked. that's the only bad case i've heard about them though.

if you are sticking to autox, you might do better w/out the front bar. it could make the front too stiff. if you are going to track events as well, it may be more benifitial. it all depends on the rest of your setup as well.
