DETAIL
DETAIL
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.
The XRAY rear alu lower suspension holders provide even greater 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 Off-
Road Set-up Book (#209099).
The tables describe the amounts of rear anti-squat, rear toe-in, rear track-width change depending
on the combinations of eccentric bushings used with 0 and 1mm, 1° offset. The 0.5mm, 0.5° represents
the half change.
Anti-Squat Example:
0(RR) - 0 (RF) = 3°
0(RR) - 0.5 (RF) = 3.5°
0(RR) - 1 (RF) = 4°
