I used the bfast kit (balls and thrust) to rebuild my pucks and it seems to be way smoother than the stock MIP kit stuff. Its almost as good as the bfast on the stock kyosho stuff. I did sand my rings flat on a piece of glass with a wet sandpaper stuck to it and the ring on the female outdrive.
The pucks is a must have for me. I do not miss replacing the driveshafts every month (with the stock Kyosho drivetrain with had flat spots fast).
