The car is lowered by a 3-thread chassis version KW, adjustable in several parameters (height, pressure and tensile dampening), which also provides for fresh driving dynamics. The three-part screwed Work VS XX-light-metal wheel rims with their stars in matte "Gunmetal" are also put in the best light this way; at the front, the 9x20 inches ET32 size is used at the rear even a full 11x20 inches ET32. The fine 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. The Eisenmann end muffler with its 76 millimetre double-end tube emphasises the deep six-cylinder sound of the Z4 3.0i audibly. JM Cardesign 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.
