E90 3.64 Performance Differential
This was the diff I had on my brand new 2006 E90 330i 6MT for about 15K miles. It was for the automatic E90 so it had the lower axle ratio. I believe it was 3.64. The manual trans E90 had a higher ratio. We noticed that the car would launch quicker off the line. However, I switched back to my stock rear axle, because I was tired of shifting and wanted better gas mileage. It has been in storage since around 2010. |
