Ive been driving my car since last Friday with the 3.73 diff (my car is a 318i, so it had the small case 4.10) but my gears kick ass now. Its nothing major in the 1st and 2nd gear but, 3rd, 4th, and 5th kick ass cuz they're taller. So now in 5th doing 70mph (not sure the kph on that) but im only at 3000rpms instead of being just above 4000rpms. Its quiet nice and i get better gas mileage.*th-up* :D :D :D *th-up*

I love the 3.73 in my 318is. It is the perfect gear to have. Excellent for around town driving and it still scoots like hell.

I roll door to door with 318is's with 4.10 diffs.
