- A car that is driven in the dirt or has tall tires might need lower gears than street car.
- Tall top gears can decrease engine noise on the highway and increase fuel mileage. Be careful not to choose a taller gear ratio than your engine will be able to pull.
- Engines that run at high RPM with narrow power bands will need much closer gear ratios than low revving engines that have broad torque curves.
