Input a rollout you want to run and then it works out the best Spur and Pinion combo. But then you have to find out what size spurs work with what cars.
i.e try putting a 100 spur 48 pitch into a TC3

I have a rollout calculator that does that if anyone wants. (ie select all your pinions and spurs first, then enter desired rollout and it will give you closest combo.)
let us know and I'll email it to anyone who wants...
