Next we unbolted the lower control arm.
With the stock lower control arm removed (upper) we were ready to install the new Steeda S197 Mustang Front Lower Control Arms with X11 Extended Ball Joints.
You can clearly see the difference in the balljoint location of the stock control arm (left) and the Steeda extended ball joint (right).
The rear bushing appears to be identical between the old and new arm. Its very common to change this bushing to a smaller diameter and Delrin or polyurethane bushing to reduce unwanted alignment changes when cornering. This is a big problem on old, worn-out bushings but since our car is a dual purpose street/track car, we didn’t want the increased Noise Vibration & Harshness (NVH) of a stiff bushing and decided to use a new large diameter OEM style bushing because they hold up quite well and don’t affect the geometry much when new.
The new lower control arm is installed and the spindle is reattached.
The extended stud moves the pivot point of the balljoint down, thus changing the angle of the lower control arm and thus, changing the instant center and roll center of the suspension.
