The M Sport also comes with staggered, light weight 18" alloys with summer performance tires. This is a major upgrade over the standard square set-up with all seasons that are found on the Sport line or Luxury line.
For Canadian buyers, the Adaptive M Suspension is only offered with the 335i M Sport package, as are the optional M Sport brakes.
