I wouldn't do it. It's also another form of stability, straight line performance. You take those off, it will be that much more unstable on a launch. As you know, cars don't launch straight, they have a bit of a torque to them. And I would think less body flex is better...unless you have some serious sway bars on there.
I maybe totally off though.
And I've heard rumors of rubbing the tires on the fenders.
