Megan Rear Roll Center Adjuster Ball Joint 240sx S14 - Pair

ROLL CENTER INFORMATION:

Front roll center is determined by the angle of the lower control arms and the angle of the upper strut mounting points. These angles, drawn in space, determine the instant centers for the front suspension (instant centers are the points that the entire suspension moves around during body roll). Then take a line from each instant center to the middle of the tire tread on the opposite side, and where these lines intersect, there is your roll center.

Rear roll center is determined by the use of the angles of the upper and lower control arms to determine the instant centers of the suspension. Then, just like the front, take a line from each instant center to the middle of the tire tread on the opposite sides. The intersection is your roll center.

Roll center angles must be measured from pivot point to pivot point. Modifying merely the angle of the arm doesn’t do anything at all. Most of the “RCA” ball joints don’t do anything besides move your arms closer to the ground.

NOTE: Due to the complexity of the installation, professional installation is REQUIRED!
