What pinion gear should I use on the SNRC R3-G/C/Pro?

It depends on your motor and the track. In the 1/10 4WD touring/gt class, racers gear by final drive ratio: 6T and below near 7.34, 13.5T near 4.51, 17.5T near 4.51, 21.5T and up near 3.65. On the R3-G/C/Pro's stock 116T spur that is about 30T for 6T and below, 49T for 13.5T, 49T for 17.5T, 60T for 21.5T and up. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the R3-G/C/Pro selected.

What is the internal ratio (transmission ratio) of the SNRC R3-G/C/Pro?

The R3-G/C/Pro has an internal ratio of 1.9:1. Final drive ratio = spur ÷ pinion × 1.9. With the stock 116T spur, a 20T pinion gives an FDR of 11.02 and a 52T gives 4.24.

How many teeth is the stock spur gear on the SNRC R3-G/C/Pro?

116 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
