Yeah the BMT is a cool car. Belts are far superior than shafts when it comes to power transfer.
There is a guy that runs one at Blue diamond and it's hooked up. It's a large 1/8 scale with a two speed and ball diffs, Although I can't imagine the ball diffs lasting a long time, It's still nice to see new additions to the class. Just like real GT. Run them all together, score them separately!
