Cst System; Braking System - Ferrari F430 Spider Owner's Manual

CST system

CST is Ferrari's acronym for Traction and
Stability control. The CST is composed of
two main systems:
VDC Vehicle Dynamics Control,
through the braking system;
Vehicle Dynamics Control,
ASR
through the engine torque;
as well as the always active secondary
systems such as ABS, EBD, etc.
In order to have optimal control in different
driving and grip conditions, four different
setting levels have been designed.
Level 1: helps ensure stability and
maximum traction on any type of
roadway, both in low-grip ("Low
Grip" position) and in very low
grip (ICE position) conditions,
by means of the engine and
brake control.
Level 2: helps ensure stability and
maximum traction only in
medium- to high-grip conditions
(SPORT position), optimizing
engine and brake control.
Level 3: enhances the racing features of
the vehicle, helping ensure (but
not in all conditions) a good
level of stability (RACE position)
by reducing engine control to a
minimum and making best use of
the brake control.
