The original Mini Cooper "S" had a gearbox final ratio of 3.44:1. At 65 MPH the engine is turning about 4000 RPM. Not only can this make the Mini Cooper driver go mad with the noise but the poor Mini Cooper engine can not take this abuse for the extended periods needed to traverse US highways.

The later model Mini Coopers use taller tires and have 3.1:1 transmission final drive gears as standard. The original stock Mini Cooper "S" engine only put out 72BHP when new, while today most Mini Cooper owners are not happy with much less than 100! With the increased horsepower at hand, the Mini Cooper can pull a much taller gear without giving up much acceleration.

If you’ve decided the FD fitted isn’t what you want, changing the FD is possible without separating the engine from the gearbox. Removing the diff case will allow you access to the diff assembly to change the crown-wheel, and access to the gear-change linkage.

Selecting the right final drive ration is a subject worthy of an entire book to explain the whys and wherefores, and also causes much consternation on the part of the transplanter. Much confusion’s spread over which gearbox has the best ratios, is best to use, and with which FD. For a detailed account on this and covering all gearboxes fitted as standard to the Mini, see the relevant separate articles 'Gearbox - Standard production gearbox types'.
