JM Cardesign from Bergheim, Germany, released their program for the BMW Z4 E85. The tuner fitted the “old” Z4 with the front pieces of the new E89 model. The front bumper and grille were modified to match the headlights, mudguards and bonnet of the E85.
The rear wheel runs were extended by about 30 millimetres on each side, and the wheel running edge was then re-built in the “original” look. Of course, this widening also required adjustment of the rear apron and side sills to the new situation. The latter also had ventilation openings integrated that facilitate the cooling air flow to the rear brake systems.
Before the vehicle was re-painted from silver to solid black in the in-house paint shop, the Germans made the antenna, which is usually located on the rear left mudguard, vanish. It is now invisibly placed in the rear bumper. The door handles, side mirrors and side indicator lights in a BMW logo shape at the doors were also equipped with coming-home-lighting LEDs.
The car is lowered by a three-thread chassis version KW, adjustable in several parameters (height, pressure and tensile dampening). The three-part screwed Work VS XX-light-metal wheel rims with their stars in matte “Gunmetal” at the front are the 9×20 inches ET32, at the rear even a full 11×20 inches ET32. The wheels were equipped with Dunlop Sport Maxx high-performance tyres in 245/30R20 and 285/25R20 respectively.
The long front end of the vehicle is given added stiffness by the Wiechers dome rod installed under the bonnet. Eisenmann provided an end muffler with 76 millimeter double-end tubes.
The German tuner took action in the interior as well. Various interior parts like the dashboard cover, entrance bars, steering wheel spokes and the gear knob were painted the same colour as the car.
