The BMW Z4 gets tuned by 3D Design and in these pics and video we can see the style upgrades to the car. Playing the sports aggression card, 3D gives the Z4 a new front splitter, side skirts and a rear extractor made from carbonfibre. A new aerodynamic feature is on the rear boot area, too. The Z4 by 3D also has a new range of four exhausts and 19-inch wheels. The interior only gets minimal upgrades with an aluminium pedal and three dials introduced in front of the gearstick. See the video after the jump.
