The complete chassis and suspension of the Turbo Coupe is significantly lighter than that of its predecessor. The four lightweight spring struts alone reduce the overall weight of the suspension by 5.3 pounds (2.4 kg). Right for the ride The shocks are all under the purview of PASM. Reacting to road and driving conditions, PASM adjusts the shocks individually, altering their firmness within fractions of a second. The driver selects one of two settings, Normal or Sport. The Normal mode provides a softer ride, with the system automatically switching over to a more sporting program as the driver becomes more aggressive. In Normal mode, PASM delivers a more comfortable ride over various road surfaces than a system with conventional shocks. The Sport mode activates a harder shock control map, comparable to the typical features of a sports suspension, and acts to minimize body roll during hard cornering. For the Turbo Coupe, Porsche engineers have enhanced the system to work in conjunction with PTM all-wheel drive and Porsche Stability Management (PSM). Constantly adjusting to the driver’s style as well as conditions, these systems help the driver maintain control without intruding or coarsely wresting control from the driver. The result is an extraordinarily high-level of driver confidence while enjoying the car's impressive traction and high-speed stability capabilities. The Turbo Coupe has power-assisted, variable-ratio rack-and-pinion steering as standard. The steering wheel is adjustable for both height and reach. Deceleration to match acceleration As befits any Porsche Turbo, the 997 Turbo Coupe boasts extremely effective brakes. The all- disc, antilock brake system uses large, 13.78-inch (350-mm) diameter, cross-drilled, internally vented rotors and fixed calipers at all four wheels. The front brakes have the same six-piston calipers as the Carrera GT, while the rears utilize four pistons. The caliper pistons have ceramic inserts which insulate them and help keep heat from transferring to the brake fluid during long periods of hard braking. The brakes themselves are cooled by carefully directed airflow. In front, air moves through two openings in the front spoiler to a wide duct in one of the front underbody panels and on to the front axle. For even greater stopping power, the Turbo Coupe is available with Porsche Ceramic Composite Brakes (PCCB) as an option. Besides replacing the metal rotors with ceramic composite, PCCB brings rotors that are almost eight percent larger than standard: 14.96 inches (380 mm). Among the benefits of PCCB are a 50-percent weight reduction compared to metal brakes, quicker response, and superb resistance to fade and zero corrosion. Four rubber patches To manage the drivetrain's power and ensure traction, the Turbo Coupe rides on massive 19-inch wheels and tires. The high-speed rated tires are 235/35ZR19 in front, and the rear ones 305/30ZR19.
