Wes, that video was shot at Knob Creek Range, and the WhiteCastle is in Shepherdsville. I know the owner of the tank and the loader/commander. That video was made a few weeks ago.
I have done the same thing they were doing, and I suspect that there was a bunch of tannerite in that engine compartment. That tank will go over that car. I've done it before in another M5, but the owner doesn't do it because he doesn't want to risk damaging the track or suspension.
The rubber pads on most M5 tracks are dry rotted and will fall off with little use. The guy that is the loader in the video remanufacturs the tracks with new pads, but it aint cheap, and his formula wasn't perfected the last time we talked about it.
Any way cool video; I'll have to call my friend.
