REAR ARM ASSEMBLY
Attach the #3863 rear arm front mount (with the "R" molded into
mount--see below for location) to the chassis with two #6292 screws.
Slide the #3866 inner hinge pins through the #3890 rear arms. Slide
the pins with the arms into the #3863 rear arm front mount.
Place the #3863 rear arm rear mount (with the "R+3+2" molded into
the mount) on the #3900 rear bumper. Align the rear arm mount and
bumper with the two hinge pins and slide together. Tighten it down
with two #6292 screws.
By changing arm mounts you can adjust toe-in and anti-squat. For
more information about the rear toe-in and anti-squat settings, see
the tuning section at the rear of the manual.
