Yes, this is an odd "Do you remember...", but I was thinking about this the other day. Top Thrill Dragster used to have a spoiler and large tires on every train. These special parts made the trains look like real dragster cars. Unfortunately, due to a not very serious incident where a tire became loose on one of the trains, this scenery was completely removed. Today, you can tell it was there because of the round, black part on the back of the train.
