Larger gears will result in higher top-end speeds while smaller gears provide more torque. For quicker acceleration, it is recommended to go for a smaller pinion gear (with fewer teeth) and a larger spur gear (with more teeth). Your car will accelerate off the mark very quickly with more torque, and you'll also benefit from cooler running temperatures, extending the life of your motor and ESC. Always consult your vehicle owner’s manual for proper gearing ratios and temperature ranges to keep your electronics safe.
