The reason that Stealth is currently not experiencing many rollbacks is, although partially to do with the weather, because they have taken Car 2 off the track. Any visitors of 2008 will distinctly remember that it was car 2 that did most of the rolling back, due to friction or something in the wheels. Thorpe park have, because of this, taken this car off the track and are using it as the spare car, and car 3 is now one of the main cars on the track, along with car 1.
