I see i'm going to need a stable of pinions in pan car racing lol.
I guess I'm going to grab a handful of pinions to get me in the 50 to 60mm rollout range and actually run the car checking temps to fine tune.
There are a few phone apps for roll out as well
I use RC Ratio
You can even save data, chart for different spur sizes, car models, etc...
