 The pressure is gathered in an accumulator which is controlled using gas pressure, by adjusting the pressure in each accumulator, the stiffness of the suspension is adjusted for different driving conditions.A new front splitter and redesigned wing blades increase downforce by 24% over the 12C while the new tyres contribute to improved handling.The new rear diffuser is based on the bumper/diffuser concept and is carried over from the 12C GT3 race car.
