E36 325i final drive

I was wondering if it's possible to change the final drive without worrying about the diff and other stuff.
Also which f/d would you recommend?

The final drive isn't necessarily the whole diff. You can swap the crown wheel and pinion from any same sized diff.

I've got a 4.10 from the states to go in mine. Any 188mm crown and pinion can be fitted to the "medium" sized diff.

Bear in mind altering the final drive ratio will have an effect on your top speed gearing. The 4.10 diff I have limits a top speed of around 115mph with the standard rev limit. Remapped to 7200 rpm, ~135 should be possible.
