POS = Piece of Shit.
Bad luck on the gearing problem, but those BM are rather quite fat, but the cooling fins are so cool looking its not so bad having to stick with a normal tranny and buggy ratio diffs. On the up side, if you did go to a centerdiff unit eventually, you would only have to change the ring & pinion gears on the front and rear diff to make them Pro/truggy ratio, much cheaper than a pair of new diffs.
