This graphite centre link is intended for 1/10 scale YZ-4S touring car use as an RC suspension tuning piece, not for any road vehicle. It supplies three selectable tie rod mounting holes so you can alter Ackermann without replacing steering blocks or uprights.
Fitting the link means removing the original centre link and refitting with the current steering linkage fasteners; always check for full steering travel clearance at each pivot before final tightening. Because the material is graphite, avoid overtightening bolts which can create stress risers in the part.
Practical tuning notes: inner pivot positions tend to increase inner wheel steering for a sharper turn-in feel, while outer positions cut inner wheel angle to aid stability on corner exit. Any changes should be reviewed in conjunction with toe and servo travel to preserve consistent steering behavior.
