One of my original concerns was that the bodies would be too flimsy and prone to damage. So far it doesn't seem to be a problem. I guess any damage they might receive is likely to be more realistic than the cars with hard plastic shells. Most of the modifieds I've watched around here tend to look like popcorn balls by the end of the season.
These classes such as the late models & the modifieds all run slab sided aluminum panels and would be easy to duplicate in a scratch built slot car. The exact size of each car isn't the same as every other one on the track because of the way they're made. That gives me a lot of leeway when it comes to making bodies to fit various chassis and less concern about dimensions being off.
