ECCENTRIC BUSHINGS HAVE TWO DIFFERENT OFFSETS FROM
THE CENTER.
Middle position = 0.5° or 0.375mm from center.
Outer position = 1° or 0.75mm from center.
The XRAY rear alu lower suspension holders provide great range of adjustment for the rear suspension. Using different combinations of eccentric
bushings, fine adjustment of rear anti-squat, rear toe-in, rear roll center, and rear track-width can be obtained. For more information about the
influence of rear anti-squat, rear toe-in, rear roll center and rear track width on car handling, please refer to HUDY Set-up Book (#209100).
The tables describe the amounts of adjustment using the center and outside positions of the eccentric bushings.
The middle position eccentric bushings allow for finer adjustment increments.
ANTI-SQUAD Example:
The track-width is directly influenced by the size of
the wheels and tires used.
0(RR) - 0 (RF) = 2.0°
0(RR) - 0.5 (RF) = 2.5°
0(RR) - 1 (RF) = 3.0°
