As with previous RS models, there was an extensive weight reduction process. The doors, front wings, roof and hood are made of carbon fiber reinforced plastic (CFRP). Inside the backs of the seats are made entirely of the same material. If that’s not enough weight loss, you can always opt for the expensive Weissach package. With it, the aforementioned parts are now exposed carbon, while suspension components such as the front and rear anti-roll bars are also carbon fiber. This also opens the door for magnesium wheels to save another 17.5 pounds.
The GT3 RS will have three driving modes: Normal, Sport and Track. Drivers can adjust a number of settings right from the steering wheel. The Drag Reduction System (DRS) button is on a rotary slider on the left side of the wheel, while active suspension control, torque vectoring differential, drive modes and stability and traction control systems can be adjusted via knobs below the wheel. Porsche also says the Weissach package adds a more precise pressure point and a more easily perceived click to the movement of the paddle shifters.
