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 new 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° off set. The 0.5mm, 0.5° represent
the half change.
Example: 0(RR) - 0 (RF) = 3°
0(RR) - 0.5 (RF) = 3.5°
0(RR) - 1 (RF) = 4°
