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 S14-3/D'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 S14-3/D selected.
What is the internal ratio (transmission ratio) of the SWORKz S14-3/D?
The S14-3/D 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 S14-3/D?
81 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

Out of the box the S14-3/D runs 800 cst front, 650 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 S14-3/D come with?
The kit springs are A4-BK (#SW-115155) front, B3-BK (SW-115156) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
What diff fluid does the SWORKz S14-3/D come with?
The kit diff fluid is 10,000 cst front, 7,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
