It depends on your motor and the track. A hotter motor (lower turns, higher KV) takes a smaller pinion; a tight track wants a lower gear than an open one. Start near the middle of the pinions the TC7 shipped with, run a few minutes, and check motor temperature before going up a tooth. The So Dialed Pinion Recommender gives a starting pinion for your motor where we have class data.
What is the internal ratio (transmission ratio) of the Team Associated TC7?
The TC7 has an internal ratio of 2:1. Final drive ratio = spur ÷ pinion × 2. With the stock 87T spur, a 15T pinion gives an FDR of 11.60 and a 35T gives 4.97.
How many teeth is the stock spur gear on the Team Associated TC7?
87 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

The kit springs are Blue 15.9lb/in (#31717) front, Blue 15.9lb/in (#31717) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
