Hello all,

Have a few questions. Just pulled out my NIB F103 15th and getting ready to build it.

Are the stock spurs the only ones that can be used, or can aftermarket ones be used as well? I noticed the diff only takes 6 diff balls; with a aftermarket spur I suppose more balls can be used, if indeed possible for this car. Also, I noticed that the stock spur is 04 pitch. I'd rather use a normal 64p so I have access to all my pinions instead of having to buy a new batch of tamiya pinions.

Next question: Tires....What does HBR stand for?

Last question: Can someone share a good starting point setup for a small/medium track carpet track? If you know what the Norcal indoor carpet track looks like then you know what I need exactly.

Thankx in advance.
