1. I don't use the body holes at all. They are not even reamed at all in my bodies.
2. I shaved the body posts and added velcro on the shaved tops.
3. Used small pieces of scrap lexan with shoe gooe to reinforce areas were shock tower meets the body during a crash.
4. Used velcro on the sides of chassis/body
5. Used gorilla tape all over the front area and back areas

My body looks new (so far), but I barely crash with my truggy.
I have had some nasty crashes with my buggy though and body reinforced this wasy has held pretty good.
