It depends on your motor and the track. In the 1/10 FWD touring/gt class, racers gear by final drive ratio: 17.5T near 4.51. On the Cero Sport M FWD's stock 102T spur that is about 43T for 17.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Cero Sport M FWD selected.
What is the internal ratio (transmission ratio) of the 3Racing Cero Sport M FWD?
The Cero Sport M FWD has an internal ratio of 1.9:1. Final drive ratio = spur ÷ pinion × 1.9. With the stock 102T spur, a 36T pinion gives an FDR of 5.38 and a 47T gives 4.12.
How many teeth is the stock spur gear on the 3Racing Cero Sport M FWD?
102 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
