The Tamiya Mini 4WD 4mm Hex Post Set, provided by 3Racing, gives a neat, serviceable upgrade for model builders wanting firmer mounting options. The kit focuses on straightforward improvements to chassis rigidity and setup versatility.
These black hex posts are intended to act as firm support posts for body and accessory mounts, reducing unwanted movement. They suit many current Tamiya Mini 4WD chassis designs and are easy to fit into common mounting positions without major changes.
Fitting the 4mm posts can sharpen alignment and reduce chassis flex under load, which helps with predictable handling during heats. They are a practical upgrade for anyone tuning ride height and balance for different track surfaces.
