Hartge has now joined the fray. Hartge, which likes to be known not as a tuner but an auto manufacturer, because of their ability to re-craft cars from the inside out, have now apparently turned their attention to the newest BMW, the 550i, 535i and 530d GT.

Hartge has shod the 5er GT with 22" wheels coupled with a lowering kit (30mm). Small interior touches are also made available, but I expect in the future Hartge will tackle a full engine rework as well as exterior styling kits.
