USVTA gearing for Type R

Hi All,

What's the magic gearing combo for a LiPO / 21.5 / JRXS 1.83 tranny for USVTA (assuming track is large enough that you want the max 4.2 FDR)?

I started to work the math...... I saw a 115 spur & 44 pinion would be almost dead nuts on, then realized that nobody makes a 115 spur (I don't think)

So, I'm opting to see if anybody already went through this???
