BMW M3 and M4 by AC Schnitzer

AC Schnitzer recently presented new tuning packages prepared for both the BMW M3, and the M4. The tuning firm offers packages for the 3 liter S55 six-cylinder engine that originally produces 431 hp, but with the tuning package installed it can produce 510 hp with 645 Nm of torque. The increase in horsepower comes from a new air intake filter, a new exhaust system with valve and of course a reprogrammed ECU.

The company also provides either lower springs at 25-30 mm forward and 10-15 mm at the back, or RS adjustable suspension which can reduce the distance in front of 30-40 mm and 30 mm at the back. The car features a new aerodynamic body kit consisting of a front spoiler, a rear spoiler, new side mirror caps and a diffuser, all made of carbon, with changes being completed with the new wheels, available in 21 inches.

The interior of the cars features aluminum pedals, a new parking brake handle, a new gear knob, an aluminum cover on the iDrive and plush carpets.
