Hi All,
I am an E46 M3 Driver, and hear lots of things about people using Z4 diffs to change ratios, does anyone know about this ?
I've heard there is a 4,1 diff available ?

The diffs in the z4m and m3 are to all intents and purposes identical, certainly the ratios are the same.

No worries. If you want a 4.1 diff built I hear you could do worse than these guys http://www.jcracing.info
I think the only parts e46 guys like to 'nick' from z4s are the steering racks (z4m coupe has the fastest BMW rack available as far as I know) and the offset lollipop bushes for the fcabs which will give you more caster.
