The ERS consists of three semi-active automat-
ic modes (T-1, T-2, R-1) and three manual set-
ting modes (M-1, M-2, M-3). When an automatic
mode is selected, the SCU will adjust the com-
pression 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
