Fitting Bilstein & Eibach Suspension To My Rebuilt BMW E91

The underside is painted, protected, and ready for assembly! In this episode, we are finally rebuilding the entire rear end of our clean-title N57/M57 manual BMW E91 Touring to get it completely track-ready for the Nürburgring. We transform our fresh chassis by hand-pressing a full set of yellow and purple Powerflex polyurethane bushes, bolting up the heavy-duty 325d inline-six diesel differential, and running custom lines. To top it all off, we upgrade the suspension geometry with a premium set of Bilstein B4 gas dampers paired with Eibach Pro-Kit progressive lowering springs! Watching this pristine, high-spec rear axle bolt back up into the car and finally lowering the wagon down onto its new wheels is the ultimate mechanical payoff for weeks of hard garage labor.
