Seven months later and famous german tuner Hartge, offers an upgrade to the body kit and wheels revealed back in May. While the initial kit focused mostly on the wheels, exhaust system and slightly upgraded interior options, the new offerings are far more extensive.

For the exterior, Hartge has created a new front apron that covers the air inlets, carbon fiber mirror caps, a discreet boot lid spoiler, a wind deflector, pin stripes and a four-piece exhaust system. The exterior kit can now successfully compete with the M Sport Package unveiled recently by BMW.

Known for their wheels, Hartge offers an even larger variety of alloy wheels, ranging from 18 to 20 inches in size. The ride has also been lowered due to a new suspension kit.

Inside, new upgrades are available, starting with a new set of aluminum pedals, instrument cluster and Hartge branded floor mats.

No engine upgrades are available at the moment, but expect next year to see a new engine kit.
