Well I finally got my kit together, and all I can say is WOW! This thing wil run over anything. It seems to have lost a little of the low end snap, but I haven't adjusted the needles for the DDM pipe yet. If anyone is considering getting a 4X4 kit I highly recommend you take a look at this kit. The chassis is a little thicker than average, but doesn't have any cut outs for the differental. I used the small plastic motor mount and put a spacer under my alloy large motor mount to raise it up. The dual 805's make this thing steer like a 10th scale stadium truck. I didn't care for the tank that came with the kit so I used my old one, it's a little close to the pipe but still fits fine. Here's a few pics.
