The German tuner, Hartge has revealed a new aerodynamic kit for the 2010 BMW Z4 Roadster again. As you may recall, Hartge previously released a kit for the Z4 in January 2010 that included a buffet of options. This next kit, although slightly impressive as well, left us hungry for more and not because it was delicious, but because it was lacking substance. Based on the E89 roadster, the kit for the BMW Z4 will include a new front spoiler and lip for boot lid both made of PU-RIM. That’s it. There’s nothing else. None of these new parts are compatible with the M Aerodynamic package and prices for the kit have not yet been announced. Throw us a bone, Hartge.
