DIFFERENTIAL
COAST RAMP ANGLE
Differential ramp angles alter how much force is produced to keep the differential locked. Coast Ramp Angles affect the
differential under deceleration, with higher numbers generating less locking force and lower numbers generating more locking
force. Higher locking force will generate more understeer under deceleration.
DRIVE RAMP ANGLE
Differential ramp angles alter how much force is produced to keep the differential locked. Drive Ramp Angles affect the differential
under acceleration, with higher numbers generating less locking force and lower numbers generating more locking force. Higher
locking force will generate more understeer but will help with traction out of a corner.
CLUTCH PL ATES
The number of clutch faces affect how much overall force is applied to keep the differential locked. Treated as a multiplier, adding
more faces produces increasingly more locking force.
PRELOAD
The differential can be set with a static preload applied to the friction surfaces. Higher values produce more locking force in the
differential in all conditions, producing more understeer under acceleration and deceleration. This value will also affect mid-corner
performance, with higher values not allowing the differential to unlock as much, increasing mid-corner understeer.
ENGINE IN-CAR DIALS
THROTTLE SHAPING
Throttle Shape controls the torque mapping of the throttle pedal. Setting 1 has an S-shaped torque map with lower torque
increase at low throttle inputs but rapidly increasing torque with increasing throttle input. Setting 3 is a linear torque map, with
each percent increase in throttle application providing an equal amount of torque increase from the engine. Setting 2 is a torque
map that is more linear than Setting 1, but more S-curved than Setting 3. This setting is adjustable from the In-Car Adjustments
black-box via the PEDAL setting.
