Hi Community! I have a 2005 Z4 3.0i with M54 engine. I don't care about top speed, but I'd like faster acceleration. I found a relatively cheap differential in good condition from 2.5i. Unfortunately, European 2.5i models are equipped with a 3.23 gear ratio differential. Will this make a noticeable difference or should I look for a diff with 3.46 ratio?
The original ratio is 3.07.

Thanks for help!
