It's the front you want to remove if any. I removed mine and it transferes weight to the rear much better, and actually balances the suspension more, so the rear doesn't tend to kick around so much easier.
If you remove the rear sway bar, it will just dive to the right when you hit the gas, especailly with your HP/TQ ratings, make launches more unstable, all over suck. Most racers drag or street like a really tight rear end, that is why most drag cars have anti-roll bars in the back.
