What pinion gear should I use on the 3Racing Auper D6?

It depends on your motor and the track. In the 1/10 2WD touring/gt class, racers gear by final drive ratio: 13.5T near 9.80. On the Auper D6's stock 112T spur that is about 31T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Auper D6 selected.

What is the internal ratio (transmission ratio) of the 3Racing Auper D6?

The Auper D6 has an internal ratio of 2.71:1. Final drive ratio = spur ÷ pinion × 2.71. With the stock 112T spur, a 17T pinion gives an FDR of 17.85 and a 28T gives 10.84.

How many teeth is the stock spur gear on the 3Racing Auper D6?

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