Well, the prespective of using an /M diff in a non-M car is really interesting but using a shorter final drive ratio is mistaken (in my opinion ,of course).

There is no need to use a shorter final drive when you have a car that performs the +50% of its maximum torque from 1200revs ,like 335i.
A shorter diff would be ideal for the naturaly aspirated //M cars that needs to reach their beneficial rev range fast (which is pretty high at 5500revs+).

Again, I find impressive your whole experiment from a technical view, but in your place i would roll back to your quaife one
I 100% agree with you, which is why I chose to stick with the 3.08. If I had a chance to go taller then I would have.
