This 12mm adaptor is specified for Tamiya TA05 and TRF-416 platforms, delivering a strict 0 degree mounting position and a consistent 12mm offset. Aluminium construction supports repeatable wheel placement for lap-time focused setup and component evaluation.
In practice the adaptor stabilises wheel position when changing wheel widths or tyre compounds, enabling direct comparison runs and predictable handling feedback without altering suspension pick-up points.
Workshop notes: verify hub bore and wheel mating dimensions on the TA05/TRF-416 hubs before installation, use consistent torque values and seating technique, and inspect for axial or radial play after initial high-speed testing. This is an aftermarket accessory for RC use only.
