The 3Racing F103RM Combo Upper Deck & Servo Mount is engineered to stiffen the upper chassis area and provide a secure, repeatable servo interface for the Tamiya F103RM. This component is intended for tuners seeking measurable gains in responsiveness and setup consistency.
By increasing local stiffness around the servo mounting zone, the assembly reduces micro movement that can introduce steering variability. The result is improved feedback at the wheel and more predictable steering geometry under load, aiding precise setup adjustments.
Produced to align with the F103RM geometry, the part integrates with stock mounting points. For optimal results, fit the deck, verify servo centring, and use measured setup runs to document changes in understeer or oversteer tendencies after installation.
