ok i just bent the crap out of the rear sway bar and i only did a short burn out my car is turbo (337 WHP) and it has a 4.77 welded diff. Do i need the rear sway bar for drag racing? my car is not a daily driver.

 

You should be good without one. The upper model cars, the "GS" had the rear sway bar but not the "S" model cars. It was just a selling point that isn't necessary. Some people run one on the track or don't it doesn't really effect performance.
