Swaybar with coilovers??

You should keep your swaybar no matter what setup unless you don't care about going around turns. If it is mainly a drag car and you don't mind taking it easy around turns then you can take it off. Coilovers do not make up for a missing swaybar. The swaybar performs a much different job then the struts or springs.
 
i dont have a swaybar on the cobra and it's not that bad. you just cant go balls to the wall into corners, but with sensible driving you wont miss it. you'll be able to feel alittle more movement if you take a turn to quick but just be carefuly and you'll be fine.
