I think a sway bar will neither hurt or help you at the drag strip.The only advantage i can see from removing it would be weight savings.Leaving It could help a wheel hop issue. My car pulled high 1.6s with my cusco rear sway bar still on the car. This was with 32psi in the fuzion zri tires(235/40/17) Ill let you know what i pull on radials here in a couple weeks.
