The XRAY alu front lower suspension holders provide even greater range of
adjustment for the front suspension. Using different combinations of eccentric
bushings, fine adjustment of front kick-up, roll center, and front track-width
can be obtained. For more information about the influence of kick-up, front
track-width, and roll centers on car handling, please refer to HUDY Off-Road
Set-up Book (#209099).
Eccentric bushings have two different offsets from the center.
Middle position = 0.5 mm or 0.5° from center
Outer position = 1mm or 1° from center
