There was a guy in Europe somewhere making lexan under body covers for the popular TC's of the time. This allowed you to also run in wet conditions. This was a few years ago. They were really trick. They were similar to the driver cockpit cover of the Ralley RS4 that cam out a few years ago.
I don't remember the website though.
If you run on a parking lot with many rocks a XXX-S would be the way to go. Or one of those Tamiya cars that have a full enclosed driver train.
