Another great product from 3racing. The carbon fiber is of good quality, and it's fairly lightweight. The kit works well if you are planning to use the aluminum bulkheads.
Note that the center shaft is much longer than the stock one, so you'll need to rebuild you're center pulleys. Also, is you're planning to use a center one-way, you'll need to shim the center pulleys a bit. The washer that 3 racing provides tightens it too much, and ends up locking the one way.
My only complaint is that it doesn't come with the strap and plastic pieces to keep the battery from sliding like the TT01 carbon conversion. So keep that in mind.
