Gear Ratios; Rear Diff Spec - Acura iRacing ARX-06 GTP User Manual

GEAR RATIOS

GE AR S TACK
Gear Stack changes the gear ratios in the transmission. Two choices are available: Short and Long. The Short setting will choose
a more acceleration-focused gear set for tracks with shorter straights or slower corners, while the Long option will choose gears
more suited to high-speed tracks with long straights.
GE AR SPEED S
Each of the transmission's seven forward gears will show the approximate ground speed at which the engine will reach maximum
RPM. These values will change based on which Gear Stack is selected, but the true maximum speed may differ slightly due to on-
track conditions.

REAR DIFF SPEC

DIFF R AMP ANGLES
The Differential Ramp Angles affect the force exerted by the differential to keep both driven tires locked together under
acceleration. Lower values produce more locking force, and more locking force increases understeer during braking and
acceleration phases. Higher values will produce less locking force and induce oversteer in these situations.
CLU T CH FRIC T IO N PL AT E
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.
PRE L OAD
The differential can be set with a static load applied. 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.
