damnn bro this is so cool to see, i got a 2008 328i with a welded diff too, buts it’s an automatic😢, it gets down tho , you should definitely get some camber arms in the rear to adjust it and get better tire wear
I have a 2006 so there’s no bmw e-diff. So no I didn’t. I’m not sure how it would handle with a newer one though. The dsc kicks in sometimes in really tight turns if I’m going too fast but otherwise I can leave it on if I want and nothing really happens until I slip
