‧ Better on smooth, high-traction tracks with long fast corners.
Higher
‧ Decreases on-throttle steering.
‧ Increases car’s responsiveness.
‧ Increases weight transfer at front of car, but decreases grip.
‧ Decreases chassis roll.
‧ Use in high-grip conditions to avoid traction rolling.
‧ Better on tracks with quick direction changes (chicanes).
Rear Roll Center Effect
Lower
‧ Increases on-throttle grip.
‧ Decreases weight transfer at rear of car, but increases grip.
‧ Increases grip, decreases rear tire wear.
‧ Increases chassis roll.
‧ Use to avoid traction rolling at corner entry (increases rear grip).
‧ Better on low-traction tracks.
Higher
‧ Decreases on-throttle steering.
‧ Increases weight transfer at front of car, but decreases grip.
‧ Increases car’s responsiveness.
‧ Decreases chassis roll.
‧ Use in high-grip conditions to avoid traction rolling in mid-corner and corner exit.
‧ Better on tracks with quick direction changes (chicanes).
