Upper Arm Position Adjustment Shims

The shims influence the camber gain change.

MORE shims = less camber gain, reduced initial
steering, reduced steering sensitivity (less twitchy).

LESS shims = more camber gain, increased initial
steering, increased steering sensitivity.

Use same shim thickness in left and right sides.

The X12 has adjustable front track-width. There are 3 different
bushings - 0mm centric (included in kit), or 0.5mm or 1.0mm
eccentric (optional). Use the same bushing in front and rear, and
also use the same orientation of the bushing on both right and left
sides.

Use the proper bushing, to achieve requested front track-width.
