Holy **** people, it's not that bad. He's running a drag setup, just take the thing off. Maybe I just don't corner hard enough to notice a huge difference. You guys shouldn't be road racing on the street anyway. I barely notice it in daily driving, and it's just a little body roll, it's not gonna kill you. It's not like the car flips over anytime you're not going straight.
Edit: Oh yeah, recently I went a 200 mile each way cruise with 8 other Mustangs through the rollercoaster/motocross track style highways of NYC and NJ (We did get air on probably more than one occasion). Believe it or not, my car had no sway bar, and I'm still alive! It worked just fine, and I had no worries at any point that had anything to do with a swaybar.
