Hartge has unveiled their new aerodynamic kit program based on the E89 version of the Roadster. The Hartge BMW Z4 Aerodynamic Kits includes only a front spoiler and a hood lid lip which might offer increased downforce on both axles of the car. The Hartge BMW Z4 Aerodynamic Kit parts are made from PU-RIM and are not compatible with the model’s M Aerodynamic package. The Hartge BMW Z4 Aerodynamic Kit also sits on new rims.
