AC Schnitzer’s experts have decided to turn their gaze on the BMW M3 and M4 once again, and they definitely managed to bring these cars to the next level both visually and performance-wise. Exterior modifications come in the form of a new aerodynamic package, which includes a multistage body styling kit. At Stage 3, which is the final stage, the cars receive carbon fiber front spoiler elements such as rear and roof spoilers, racing splitters, carbon fiber mirror covers and carbon fiber side wings.
When it comes to power, these BMWs received ECU upgrades that bring their total power outputs up to 503 horsepower and 482 lb-ft of torque. This is a considerable increase from the standard figures, which were 425 horsepower and 405 lb ft of torque. Moreover, the tuners also implemented silencers on the exhaust, as well as new sound pipes and flap controls, which definitely helped out with the aforementioned power boost.
