It depends on your motor and the track. In the 1/10 2WD buggy class, racers gear by final drive ratio: 6T and below near 9.40, 7.5–8.5T near 9.22, 17.5T near 6.48. On the 22 4.0's stock 78T spur that is about 20T for 6T and below, 21T for 7.5–8.5T, 29T 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 22 4.0 selected.
What is the internal ratio (transmission ratio) of the TLR 22 4.0?
The 22 4.0 has an internal ratio of 2.43:1. Final drive ratio = spur ÷ pinion × 2.43. With the stock 78T spur, a 18T pinion gives an FDR of 10.53 and a 32T gives 5.92.
How many teeth is the stock spur gear on the TLR 22 4.0?
78 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What springs does the TLR 22 4.0 come with?
The kit springs are LF Silver (#233046) - lightest LF front, LF White (#233056) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
