BMW specialist AC Schnitzer released further details of their upgrade kit for the BMW 4 Series Coupe, now called the ACS4, ahead of its debut at the Essen Motor Show. This is a full treatment with engine, suspension, wheels, exterior and interior modifications. AC says they are reaching for the “Tuning Crown” with this car.

The visual work begins on the 4er with chromed grilles, front splitter, rear diffuser, rear roof spoiler, rear spoiler and rear skirt, all with protection foil. Two chromed tailpipe trims in the brand new “Racing Evo“ and “Sport“ styles are available to complement the sport exhaust system.

As for the wheels and suspension, you can either go for the sport springs and drop the car by 25mm, or if you like fiddling around, get the adjustable system. There is a wide range of wheels available, including Type VIII BiColor rims in black or silver, Type VIII forged alloys and forged racing rims in BiColor, Type IV rims in silver or BiColor black, and Type VI rims in BiColor.

Inside, AC Schnitzer BMW 4 Series comes with “Black Line” aluminium handbrake handle, aluminium pedal set, AC Schnitzer foot rest, keyholder and velours foot mats, as well as AC’s signature gear knob with the digital gear display.
