I was thinking, if they had a spot where they have something that looked like breaks that appeared after a str8 spot on the track where a set of wheels would attatch. This would keep it from swinging from side to side on the inversions of the ride. I dunno about stresses though. The flat spots may be boring also, it could happen during a str8 drop though. Just a thought.
