It depends on your motor and the track. In the 1/10 4WD buggy class, racers gear by final drive ratio: 6T and below near 10.66, 7.5–8.5T near 10.00, 13.5T near 7.95. On the S14-4's stock 81T spur that is about 19T for 6T and below, 20T for 7.5–8.5T, 25T 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 S14-4 selected.
What is the internal ratio (transmission ratio) of the SWORKz S14-4?
The S14-4 has an internal ratio of 2.471:1. Final drive ratio = spur ÷ pinion × 2.471. With the stock 81T spur, a 16T pinion gives an FDR of 12.51 and a 28T gives 7.15.
How many teeth is the stock spur gear on the SWORKz S14-4?
81 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What shock oil does the SWORKz S14-4 come with?
Out of the box the S14-4 runs 500 cst front, 500 cst rear (SWORKz oil), on 2 x 1.6mm front, 2 x 1.7mm rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
What springs does the SWORKz S14-4 come with?
The kit springs are 38mm US3-dot (#115186) front, L2-Dot 57mm (#SWC-115162) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
