I've never had the sway bar off my 97, but it isn't that noticible on the 88 stang. Sure, you get a little more body roll, but I wouldn't call it dangerous by any means. The biggest danger is that it takes an extra moment for you to feel what the car is doing without a sway bar. Your car just doesn't respond to the steering input as quickly, thus you could find yourself over correcting or giving too much input easily.
