To lower the roll center you would raise the inner camber link position and lower the front arm. You could also lower the outside camber link as well.
Lower
• More on-throttle steering.
• Car is less responsive.
• More weight transfer at front of car.
• Better on smooth, high grip tracks with long fast corners.

• Use in high grip conditions to avoid traction rolling.
• Use on tracks with quick direction changes (chicanes).
