Buddy Club's Extended Ball Joints (Roll Center Adjusters) are taller than OEM spec to properly level the suspension geometry back to neutral on drops over 1.5"+.  This will allow for better shock response on the front and remove all bump steer.

A must have for all track cars!!

As you track your vehicle and experience tremendous lateral G-forces while entering and exiting turns, your suspension
geometry changes; this much is common knowledge, but is often misunderstood. As your car experiences sideways
forces, the upper and lower control arms change angles in relation to one another. Most people understand this part of
the concept, and that the resulting change could pivot the center line 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.
What’s not understood is that simply “dialing in” negative camber to counteract these effects is a patch fix that doesn’t
address the changing of the suspension geometry; it merely compensates for it. The trade off then becomes less
predictable handling during turns and loss of straight-line stability due to unnecessarily increased camber, not to mention
avoidable premature tire wear. This problem is aggravated when the camber is changed by adjusting the angle at the
upper control arm; the angles between the upper and lower control arms help determine a vehicle’s roll center, and,
where the roll center occurs in each side of the suspension.
To counteract this problem, Buddy Club has released the P1 Racing Extended Ball Joint, a taller 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, especially when
used in conjunction with an upper control arm camber adjustment kit. The roll center adjuster is an essential part of any
tuned suspension on a street or track vehicle lowered 1.5 inches or more.  Vehicles equipped with adjustable upper control
arms or camber plates should consider these necessity.
