Final Drive?
Its the gear ratio of the last (final) gearset which drives your differential. If it was a rear-drive car you'd call it your ring&pinion ratio or your rear end ratio.
For example on my GS-R 5th gear is 0.787:1 and final drive is 4.40:1 so multiply them together... The engine turns 3.46 revolutions for every one revolution of the wheels.

excellent explanation...and it also can effect your excelleration and/or top end speed, depending on wether you have a conservative 4.4 or something a little more burly like a cusco 5.0 FD.
