 The air brake which is carried over from the 12C is now controlled by an onboard computer which uses the data gathered from accelerometers in the car in order to counteract lift.The 650S also makes use of a Drag Reduction System (DRS) for reducing drag and to improve the car's aerodynamics.Like the 12C, the 650S comes standard with a carbon ceramic braking system manufactured by Akebono but the problems related to braking response in the 12C were addressed and improvements were made.
