Megan Rear Roll Center Adjuster Ball Joint 240sx S13 - Pair

ROLL CENTER INFORMATION:

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!

Application: 1989-1994 Nissan 240SX/180SX/Silvia (S13)
