If there is one thing AC Schnitzer excel at, it's suspension, and our RS adjustable suspension package is our very best product. Extensive R&D by AC Schnitzer engineers and setup by AC Schnitzer test driver Manfred Wollgarten on the road and at the Nurburgring result in a package that gives incredible control with sublime ride quality. There simply is no better suspension package for your M car. Adjustable for ride height between 30-40mm lower than stock, and compression and rebound damping independently, this package comes supplied with AC Schnitzer's recommended settings for fast road use.
