Yep any A arm that has Hiem Joints where the arms mount to the frame require adjustment. You dont just bolt them on and go. You have to use a deg finder to measure the angle between the Upper and Lower Ball Joint. Then you go back and turn one joint out to ethre move the ball joint forward or back, changing the angle between the upper and lower ball joint. It is a real pain in the butt to set correctly.
Where the LSR's have 2 spacers that go on the top a arm bolt. You ethire put both spacers in front of the a arm, both behind, or one on each side.
