  15. Spherical-bearing lower arms
  16. A slight correction of arm position lets the suspension work to its full potential! One weakness of lowered cars is the upward angle of their lower arms. The angle may be small, so many people notice it but do nothing, thinking it cannot matter much. Yet that slight angle puts the suspension arms near the limit of their operating range. With the lower arm horizontal, both bump and rebound gradually change toe toward toe-out, though it may briefly become toe-in. That is the standard condition, but when the arm angles upward it is already… [continued]

  18. Revising the suspension geometry of a lowered car removes unstable behavior in bump and rebound, making the car respond directly to driver inputs. Roll-center correction is particularly effective on lowered cars, so we will explain how to optimize the roll center. Before installation of roll-center-adjusting spherical-bearing lower arms.

  25. The arm pivots use spherical bearings, eliminating the deflection of factory bushings for more direct feel and smoother movement. [OCR damaged]
