Brake system
The large wheels conceal high-performance brakes. All four discs
are ventilated. They have a diameter of 310 millimetres on the rear
axle and 370 millimetres on the front axle. The front friction rings
are drilled for maximum heat dissipation and are connected to the
aluminium brake drums by hollow-drilled pins.
Four-piston calipers, painted black and sporting the RS logo on the
front axle, clamp the discs with a vice-like grip. The calipers are
also manufactured from aluminium - this reduces the unsprung
masses.
Note
ESP Sport mode should only be activated for agile handling and sporty driving if the road, weather, visibility and traffic con-
ditions permit.

Electronic stabilisation program (ESP)
The ESP electronic stabilisation program is optimised for dynamic
driving, but can be deactivated in two stages using the TCS/ESP
button E256 in the centre console.
First stage (Sport mode)
In the first stage (Sport mode), traction control is disabled and the
brakes intervene somewhat later than in normal operation.To
select, push the ESP OFF button briefly. The ESP warning lamp in
the dash panel insert lights up and ESP Sport comes up on the
driver information system display. Driving stability is limited in
Sport mode.
Second stage (complete shutdown)
In the second stage, ESP is completely deactivated. To select, push
the ESP OFF button for longer than 3 seconds. The ESP warning
lamp lights up and ESP off comes up on the dash panel insert dis-
play. When ESP is deactivated, TCS is disabled at the same time.
