Every year, Z3 (and now Z4) owners make the trek to Spartanburg, SC, where the cars were made. This year, TC Kline Racing brought their Carbon Coupe, based on the BMW Z4 M Coupe. Z3 owner, photographer, and attendee Doug Richardson took some nice photos of the "TRAK STR."

TC Kline Racing recently completed development of its \221Carbon Roadster\222 \227 a re-skinned BMW Z4 covered entirely in carbon fiber. Based on the Z4 M, the car has the 346 horsepower engine from the M3 coupe. It weighs just 2,680 lbs \227 that\222s 400 lbs less than the standard Z3M, and 700 lbs less than the M3!

TC Kline Racing 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.
