The Carbon Coupe weights 2,740 lbs., has 342 hp and corners with 1.06G grip. Take a minute to soak that in. The CC weighs less than a Honda S2000, has the HP of a Porsche 911, and has wider wheels and tires than a Ferrari F430. Incredibly, the CC weighs almost 600 lbs. less than a BMW M3 while maintaining the same power, drive train, and suspension.
The Body; Like the CR, the entire skin of the CC is manufactured from Carbon Fiber Composites. The changes to the Z4 M Coupe bodywork are a direct result of the application of the principals of �form follows function�. Walk around the CC and you will not find any body lines which do not serve as an extension of function. The Carbon Coupe body work incorporates aerodynamic performance enhancements with a front air dam, front wheel house vents, and side skirts. The body also has all four fenders flared to accommodate wider wheels and tires. The use of carbon composites to make the body reduces the weight of the CC tremendously while maintaining a strong durable skin.
Interior: TC Kline has contracted with Recaro to produce a one piece shell performance seat specifically for the CC upholstered in Custom Leather. These light weight performance seats feature cutouts for a driver harness and have exceptional support while maintaining driver comfort. These Recaro/TC Kline seats are similar to those found in the E46 BMW M3 CSL or the Porsche Carrera GT.
The Drive Train: The Z4 M Coupe incorporates the E46 M3 Drive train. The TC Kline CC is based on that car and shares its 3.2 liter motor, 6 Speed Transmission and M Lock Differential. TC Kline upgrades the drive train with an Aluminum flywheel for quicker throttle response, improved acceleration and lighter weight. TC Kline has also developed a thin wall stainless steel exhaust system for the CC. This exhaust system is significantly lighter than the stock system and improves horse power by 12.
The Suspension: KONI Double Adjustable Coil-Over struts and rear shocks valved to TC Kline Specifications are already accepted by the BMW enthusiast as the standard for street and track performance and directly contribute to the 1.06G cornering grip the CC develops. The VVS suspension springs for the CC are made in Germany from a light weight alloy steel and TC Kline has a variety of spring rates available which allow the owner to tune the CC to their personal taste. The CC front struts are topped off with TC Kline designed front Camber Plates for quicker turn-in and steering feel and Delrin bushings replace the standard rubber bushings in the front lower arms and rear trailing arms for quicker response and markedly improved feel. (TC Kline also offers suspension bushings in Monoball or Rubber to suit driver tastes). These TC Kline components significantly reduce the unsprung weight resulting in a more responsive suspension.
Brakes: Performance Friction Corp. has created extremely rigid and light weight aluminum MonoBloc calipers for use on the CC. The front caliper is a four piston design with four brake pads for superior modulation and high brake torque and the rear caliper is a two piston design sharing the same pads. The large floating rotors have aluminum hats for light weight. The front rotor diameter in 345 mm, and 321mm rotors are on the rear. The PFC Carbon Metallic Brake Pads offer exceptional brake loads for extremely short stopping distances. These ultra performance brakes also contribute significantly to reducing the unsprung weight of the Carbon Coupe.
Wheels and Tires: The CC uses a one piece forged aluminum wheel designed for the lightest weight and strength. The CC standard front wheels are 18x9.5� and the rears are 18x10.5�. TC Kline has chosen 18� wheels to allow drivers to take advantage of a larger selection of �R� Compound tires. The Michelin Pilot Sport Cup is currently the highest performance tire available for the street. The standard sizes for the CC are 265/35x18 front and 295/30x18 rear. These Sport Cup tires produced 1.06 G cornering in a Car and Driver test driving a TC Kline Z4 using the same suspension as supplied on the CC. The Michelin PS2 Ultra high performance tire will be available as a no cost option. The PS2�s offer extended wear with less grip than the Sport Cup tires.
