There's something rotten in the state of Bavaria when BMW's M division is more keen to tune out crossovers than roadsters. While the previous-generation Z4 and the Z3 that preceded it both had M versions, the current Z4 has been conspicuously absent from the hall's of the BMW performance division. That could all change if the bean-counters see a good business case for a Z4 M, but in the meantime we're reportedly slated to get something even crazier: the V8-powered Z4 GT3.
TC Kline Racing debuted its Carbon Roadster at last year's SEMA, but we thought it was worth revisiting since we ourselves had never visited it before. The Ohio based tuner has taken a BMW Z4 M roadster and faithfully reskinned it entirely in carbon fiber, effectively shaving 500 lbs. off of the car's weight in one very expensive fell swoop. It still looks like a Z4, but with much larger fender flares to accommodate giant 19-inch wheels with Michelin Pilot Sport Cup tires.
