For the exterior, Hartge has created a new front apron that covers the air inlets, carbon fiber mirror caps, a discreet boot lid spoiler, a wind deflector, pin stripes and a four-piece exhaust system.
Inside, new upgrades are available, starting with a new set of aluminum pedals, instrument cluster and Hartge branded floor mats
Customers can also give the hardtop roadster an even sportier stance with the addition of Hartge's alloy wheels that are available in numerous designs in sizes 18- to 20-inches, and a suspension lowering kit.
After showing us its initial offerings for the new BMW Z4 that were limited to a few alloy wheel options, a dual-pipe exhaust system and a new speedometer, Hartge has taken one step further by releasing a new set of upgrades for the hardtop roadster.
No engine upgrades are available at the moment, but expect next year to see a new engine kit.
