excuse the pic quality, but i broke my digicam, so these were taken with my camera phone.
had a problem with one rim holding the out bead; i think i over-torqued it an warped the ring, as i havent had any problems since i flipped it over.
Foams are definitely needed. Too many times the tires rolled up over themselves and caused the axle to stall. Fortunately, the beadlocks apear to be holding well.
Matts battery was dead, so i towed him off the course :p Unfortunately, shortly after that it appears that i blew the rear axle. Im gonna take apart and see what happened.
