But, imho LSD (of any kind - I do run a Quaife - a worm type LSD - on the other car of mine, and frankly speaking I would NOT tell Drexler from Quaife, they behave +/- the same) is only half of the fun. Shortening the diff does the second half.
I have both cars shortened quite a lot (3er - 15% both diffs, Z4 - 17% rear one) and the increase in dynamics is overwhelming. Proportionally, the milleage dropped quite a lot, too. |
Good to know I can swap out final ratios on rear in xDrive and have no issue with AWD controller. I want to do that since the wagon is heavy and the wheels are heavy on 18x8 50 lbs each wheel and tire
