HS C O MPRES SI ON DAMPING
High-Speed Compression affects the shock's behavior in high-speed travel, usually attributed to curb strikes and bumps in the
track's surface. Higher compression values will cause the suspension to be stiffer in these situations, while lower values will
allow the suspension to absorb these bumps better but may hurt the aerodynamic platform around the track.
HS C O MPRES SI ON DAMPING S L OPE
The High-Speed Compression Damping Slope setting controls the overall shape of the high-speed compression side of the
shock. Lower slope values produce a flatter, more digressive curve while higher values result in a more linear and aggressive
compression graph. The value of the slope setting is very important in controlling bump absorption at high shock velocities and
controlling the aerodynamic platform. A lower slope will be helpful for rougher tracks in absorbing bumps and sharp impacts such
as curbs, while a higher slope will keep the suspension more rigid, which can be helpful in resisting compression and raising the
chassis above a bump in the track surface. It's important to understand that these settings will affect the range the High-Speed
Compression will have, with higher slope values producing a higher overall force for high-speed compression.
L S REBO UND DAMPING
Low-speed Rebound damping controls the stiffness of the shock while extending at lower speeds, typically during body movement
as a result of driver inputs. Higher rebound values will resist expansion of the shock, lower values will allow the shock to extend
faster. Higher rebound values can better control aerodynamic attitude but can result in the wheel being unloaded when the
suspension can't expand enough to maintain proper contact with the track.
On the front of the car, higher Low-Speed Rebound can induce understeer on throttle application while higher settings on the
rear of the car can induce understeer under braking.
HS REBO UND DAMPING
High-speed rebound adjusts the shock in extension over bumps and curb strikes. Higher values will reduce how quickly the shock
will expand, while lower values will allow the shock to extend more easily. Despite not having as much of an effect on handling
in result to driver inputs, High-speed rebound can produce similar results in terms of aerodynamic control and uncontrolled
oscillations if set improperly.
ROLL DAMPERS
L S DAMPING
The Low-Speed damping setting on the Roll Dampers will alter how resistant the damper is to both compression and expansion
during roll. Higher values will produce a stiffer shock with chassis roll, which can load the outer tire in a corner more quickly, and
lower values will soften the shock and delay load to the outer tire. Due to the Roll Damper's operation, rolling the chassis will result
in the damper compressing for one direction and rebounding for the other direction, thus both compression and rebound are
adjusted equally together.
HS DA MPI NG
The High-Speed damping setting will alter how stiff the front Roll Damper is at higher velocities, such as one-wheel curb strikes or
side-to-side oscillations. As with the Low-Speed setting, the compression and rebound values are linked as one.
