When you start talking about aftermarket tuning companies that specialize on BMWs, the name AC Schnitzer will inevitably come up in the discussion. The German tuner prides itself on being one of the best in the business when it comes to creating programs for Bimmers and that form has held true to this day. Take for example its latest project for the BMW M2. It’s loaded with upgrades from front to back and everything else in between. That includes a tuning upgrade that brings the sports coupe’s output up to 420 horsepower, 50 ponies more than the stock output of 370 horses.
