Inputs

Tire Size

Width / Aspect Ratio / Rim Size. Use the tire size from the power-dominant axle: FWD = front, RWD = rear, AWD = whichever axle gets more power.

Redline RPM

Desired Top Speed MPH

Number of Gears

1st Gear Speed Bias Adjusts the 1st-gear speed target, then automatically respaces all gears between 1st and top speed.

Power Lean / Gear Spacing Choose where you want the gearset to lean its acceleration coverage. Higher speed lean has shorter gears and more power near top speed; Lower speed lean has shorter gears and more power at lower speeds. Balanced will try to keep power between gears even. Balanced is default.

Results update automatically when you change any input.
