ok, after some more Googling, I think I've found the answer. Through a higher-numbered final drive you are putting more torque through to the driving wheels, which will give you better acceleration. But as well as decreased top speed, you'll be doing more revs to do the same speed that you usually do (e.g. 70 mph on the motorway), meaning more wear on the engine, increased engine noise and worse fuel consumption.

right i see.
