Hi everyone, Im sure its covered, and Ive been searching for about three days with no luck, so Ive come to ask, do all E90 335i have a braking diff? I know March 08 introduced a revised/updated e-diff, but what about before that? Im looking to buy a 335i 6 speed, and I prefer the car to lay down 2 tracks rather than one, perhaps the better question is, will a pre 3/08 335i still put down 2 marks? I will be throwing a lsd in there as time and budget permits. Just wondering how she will behave in the meantime, thanks!
