Owners of the Tamiya 54725 TA07 can fit these aluminium motor mount posts as a direct replacement for the original A15 pieces to get a firmer motor anchorage. The upgrade is useful when running more powerful motors where a rigid connection matters.
Compared with plastic, aluminium reduces chassis flex and lessens vibration at the motor mount. The result is a steadier drive train and crisper response when pushing the car on tarmac or prepared surfaces.
Swapping parts is simple with standard hex tools; tighten fixings to a sensible torque and avoid stripping threads. Keep the area clean and inspect fasteners periodically for long term reliability.
