Buddy Club P1 Racing Ball Joints Scion FR-S 2013-2016 / Subaru BRZ 2013-2020

As you track your vehicle and experience tremendous lateral G-forces while entering and exiting turns, your suspension geometry changes. As your car experiences sideways forces, the upper and lower control arms change angles in relation to one another. The resulting change could pivot the centerline of the affected wheel in such a way as to produce a significant change in camber, resulting in less tire contact with the ground and, subsequently, poor traction and stability.

To counteract this problem, Buddy Club has released the P1 Racing Extended Ball Joint, an adjustable ball joint that connects to the lower control arm, not the upper, thereby allowing a more correct and apt suspension geometry between upper and lower control arms to be maintained; this insures a more predictable roll center. The roll center adjuster is an essential part of any tuned suspension on a street or track vehicle lowered 2 inches or more.
