Trailing arm design

Finding out the space about 8mm thickness on lower arm inner bush bracket outside, I remembered easily movable rear bush on NCP10 TOYOTA Vitz.
This space were not produced by the shrinkage of bushing rubber material caused by aging but the originally intentional axle design, inviting progressive displacement of rear lower arm position.
This kind of method is utilized for the compliance, provocative toe correction while the lateral force was input during turning phase.

As TRD(TOYOTA RACING DIVISION) sells special parts to prevent lateral displacement of the lower arm, same kind of experimental trial may improve dull steering action of VW 1302 Super Beetle. It goes without writing, the lateral displacement of rear axle spoils astringency of steering action.

The careful checking on rear axle and suspension would be the next task to do on Super Beetle.
