The ERS consists of three semi-active automat-
ic modes (T-1, T-2 and R-1) and three manual
setting modes (M-1, M-2 and M-3). When an au-
tomatic mode is selected, the SCU will adjust the
compression and rebound damping forces
based on running conditions. For all modes and
models, spring preload is physically adjusted by
hand.
For track modes T-1 and T-2, the following set-
tings can be adjusted:
BRAKE SUPPORT: reduces nosedive (front-
end pitch from braking)
CORNER SUPPORT: increases damping to ab-
sorb chassis fluctuations for smooth cornering.
Reduce this setting for increased rear wheel
grip.
ACCEL SUPPORT: reduces rear-end squat
(rear-end pitch due to acceleration)
FRONT FIRM: hardens "H" or softens "S" overall
damping of the front suspension
REAR FIRM: hardens "H" or softens "S" overall
damping of the rear suspension
