BMW E46 3.46 Differential Upgrade

In this episode of Project E46 I discuss the pros and cons of upgrading or changing an E46 differential gear ratio. My BMW 328i comes with a 2.93 gear and it's the laziest gearing available for any E46. There are also 3.07, 3.15, 3.23, 3.46 and 3.91 diffs that are plug-and-play for the E46, well mostly. Here's why I chose the 3.46 diff from an automatic car for the street drifter E46 project car. #bmw #e46 #drifting
