final drives

[nikkiy9]

doing 60 miles at 70 is using 1/4 of a tank, yet with a better final drive it could get to 1/8th of a tank!

doubt it will get much better but you can find a list of all gear ratios in the gearbox faq in the transmission section of clubgti

Tbh for the work / cost involved I don't think you will gain anything.

Given the amount of torque the 1.4 has, i doubt it would move if you put a different finall drive in.

Slowing down to 60 would save you more money than changing the gearbox

Any savings you may make in fuel will be outweighed by the cost of changing the fd. Really not worth it.

Any modifications to a 1.4 lump are pointless imo.
