The roll center adjuster kit enables the vehicle to be lowered without detriment to the suspension system.

• Decreases body roll
• Improves tire contact patch with the road
• Increases steering wheel responsiveness
• Enables increased cornering force

When the height of a vehicle is lowered, the balance of the suspension geometry is disrupted. This causes a deviation in the roll center, which increases body roll—even though the center of mass is also lowered. The altered suspension geometry leads to a reduction in mechanical grip and places additional stress on suspension components.

By installing the HARDRACE Roll Center Adjuster, the extended ball stud helps restore the suspension geometry by repositioning the control arms closer to their original design orientation. This correction improves steering response and handling stability. Additionally, the corrected geometry reduces wear on suspension components, thereby increasing their durability.

As a result, the HARDRACE Roll Center Adjuster is a must-have upgrade for any serious driver.
