This thread goes out to any members who have completed the above rear diff swap from their MT 330i. I am really interested in doing this but I am hesitant about the nearly 15% increase in RPM's from a daily driver perspective. How much do the added revs affect the day-to-day livability of the car. I do a lot of hwy driving and fear the higher cruise rpm will cause exhaust drone (just a PE). Also did anyone notice a big drop in fuel economy especially at highway speeds? So for those who did it how much am I over thinking this. Are there any dif swaps that are plug and play (ie. no modifications to the input and output shafts)

Edit: See video on 2nd page of acceleration with new diff!
