I plan to race mine.
That is, after fabricating some substitutes for the damper stays, CF bulkheads and the bumper. I have some old PC boards which I can cut up for the damper stays. I still have to find a good substitute fort the front bumper. I don't want to scratch it up too much.
The rest of the parts are available locally. LHS have stock for the rear belt or you can come up with a makeshift tensioner and use the TA04 belts. I assume the front belt is the same as that of the TA04(?).
I still have to practice my driving. For now, I'm racing a TA03...
