Gentlemen,
Maybe someone can chime in on this topic. I just dropped off my car at a local (reputable) shop to install OEM M5 wheels and H&R springs. The shop has indicated that unlike the 550, which has self leveling suspension, to get to the rear suspension, they have to remove the rear seats. This is a first for me and I just want to hear from any fellow 535 owners who've lowered their cars to see if this is accurate???
