AC Schnitzer’s ACS7 for the BMW 7 Series is mostly a cosmetic makeover with a new front and rear skirt, rear roof spoiler, and side skirts to improve the aerodynamics. They also add a rear silencer system to the exhaust, a spring kit that lowers the car by 25 mm to improve cornering, and upgrade the wheels. To top it off they throw in new floor mats, aluminum pedals and footrests, and a cover for your “i-Drive system.”
