I've seen that show :facepalm::facepalm::facepalm: those guy make a living out of ruining cars, yeah I am sure the standard suspension layout would work fine if you fit the wheels with 25cm spacers, go right ahead.
I have my doubts whether it would fit, cause he said it has a LSD gearbox so my guess would be that it is an engine out of a FF car where the gearbox and diff are in the same unit, well that or he doesn't know what he is talking about
but if it was a toyota it would be awesome a hell of alot of work went into this but i just cant understand why he would do this conversion on a bmw when its already Rwd and well balanced...
