My Ride: 07' 550i sport; Sapphire Black/Auburn; sport package; steptronic; navigation with R.T.T.I.; heads up; cold weather package; Logic-7; BMW MOST ipod kit; Motorola V3 snap-in adapter; rear heated seats and rear shades; anthracite headliner; sirrius sat. radio; M-aero kit; OEM style 166 Wheels with 245/35-19 front and 285/30-19 rear Michelin PS2s.
Does ARS affect the car's ability to avoid bottoming out at high speeds over, i.e., dips in the highway? Or is that still exclusively the function of the springs? My 550 sport suspension seems tight enough, but looser than my last BMW (740i sport). It soaks up the bumps okay at 100 mph, but what about 120+? Does the active system maintain the same level of stiffness as speeds increase? In other words, does it get stiffer electronically/hydraulically when travelling in a straight line - not in a corner? I'm still amazed by the feeling while cornering. Its truly a great bit of kit the ARS.
