Graphite Servo Mount Plate for YZ-4S and B-YZ4SF - Yokomo S4-203PA  [S4-203PA]

Precision graphite servo mount for YZ-4S fitment

This graphite servo mount plate suits the YZ-4S platform and compatible B-YZ4SF models. The plate gives a firm, lightweight mounting surface that positions the servo relative to the chassis centreline and steering linkages to aid consistent handling during tuning.

Fitment note: the plate is intended to be used with the inner and outer post hardware listed by the manufacturer, namely the inner post (S4-203A?1, 900) and the outer post (S4-203AO?900). Those posts are separate components and are required to fix the plate and servo to the chassis.

Installation pointers: ensure servo splines are aligned before final tightening, use screws of the appropriate length for your servo case, and avoid over-torquing which can damage the graphite. Verify plate orientation matches the chassis holes and check linkage movement once assembled. This accessory adjusts servo placement and steering feel rather than altering motor or drivetrain performance.

Setup impact: changing the mount location or the stiffness of the mounting point can influence steering centring and transient response. Use the plate as part of an overall setup plan when adjusting toe, steering rate, or servo throw to refine handling.
