I'm interested in buying a Wavetrac or Quaife diff with lower gearing (higher ratio) than stock to improve acceleration. Did some of you that bought these units also change your ratios? If so, what ratios did you go with and are you happy with the outcome?

I believe these are the stock ratios:

6MT
- 325i 3.23
- 325xi 3.38
- 328i 3.23
- 328xi 3.38
- 330i 3.15
- 335i 3.08
- 335xi 3.08

6AT
- 325i 3.73
- 325xi 3.91
- 328i 3.73
- 328xi 3.91
- 330i 3.64
- 335i 3.46
- 335xi 3.46

Thanks.
