Velcro Rules !!!!! You just have to get the right velcro. And design the body mounts properly. A 3/4 inch wide super thin piece of aluminum running between the body posts on the rear with some outdoor type velcro will work just fine. Look for the stuff that will stick to concrete and unless the whole car gets in the air the body won't come off. IF you have body posts and the car hits something has to give and guess what its not going to be the chassis. Velcro has saved me lots of times. The only time I had a body fly off going down the strip was the first time out with the Plazma. Didn't have the front body mount wide enough. A lot easier to get the body on the car during those tense moments before a run as well. The funny car body I have went through 2 complete write-off's of a chassis without a scratch thanks to velcro body mounts. On the front of a rail I had a piece of velcro about 5/8 wide and an inch maybe a little mor long. Mounted to a single post about midway from the front of the body to the drivers compartment on the body. That body also survived multiple total wrecks of the chassis. Look at this pic. The body mounts are visible One at the front one midway along the body. They have white velcro on them.



And as you can see from this pic the body is intact after a massive crash that totally wrecked the chassis.



Took home the trophy though
