* These gearings are given in the Final Drive Ratio (FDR) form for standard-sized rubber tires. If you choose to use different sized tires, use the formula below (in note **) for rollout to determine the proper gearing for your tire’s diameter.

Using standard-sized tires to calculate your FDR, first divide your vehicle's spur gear by the pinion gear, then multiply that result by the internal drive ratio of the car. The internal drive ratio can be found in the documentation that comes with your vehicle. EX. (72 spur ÷ 21 pinion) x 2.5 internal drive ratio = 8.57 FDR

** Gearing is given in rollout. Rollout is determined by dividing the tire circumference (tire diameter x 3.14) by the spur and pinion gear ratio. EX. (1.75” x 3.14) ÷ (100 ÷ 23) = 1.26 rollout
