130i - Shorter rear diff options?

Hi all,

I owned a 2003 BMW Z4 3.0 that responded really well to have a rear diff from a 2.5 Auto model fitted (was much shorter)

Has anyone done this to a 130i? Would be nice to increase acceleration for track work. Do diffs from other models fit the 1 Series too?

Any recommedations would be apreciated.

o :)
