Changing the final drive ratio heavily impacts the way the car behaves. If you increase the final drive ratio, each gear will have greater wheel torque, while sacrificing top speed. If you decrease the final drive ratio, each gear will have a higher top speed, however deliver less torque. Raising the final drive ratio also means you ll be at higher RPM in your top gear, raising your engine s speed on the highway. You ll also need to correct the speedometer. How To Calculate The Top Speed Of A Specific Gear In MPH: Top Speed = ((RPM*60)/(Final Drive*Current Gear Ratio))*((Wheel Size (in.) +(2*(Tire Ratio/100)*(Tire Width (mm)/25.4)))*Pi)/(5280*12) Don t forget to check out my other pages below!
