Tamiya TA05/TA05-IFS/TA05-R/TRF-416 Aluminium 12mm Wheel Adaptor (+1 Degree) by 3Racing TA05-12/1/V2  [TA05-12/1/V2]

12mm Wheel Adaptor for TA05 Series

This aluminium 12mm wheel adaptor is designed for Tamiya TA05 family chassis including TA05, TA05-IFS, TA05-R and TRF-416, offered as Version 2 with a +1 degree toe change. It is an RC-scale wheel offset part intended to alter wheel position and small toe geometry changes without modifying hub housings or wheel hexes.

Installation is straightforward for anyone familiar with touring car wheel assemblies: remove the wheel and existing adaptor or hex, fit the 12mm adaptor to the axle/hex interface, and secure with the original wheel nut or retaining hardware. Use the correct hex driver and check thread engagement; small alignment checks on a flat surface are recommended before track use.

As a tuning item, this adaptor modifies wheel offset and introduces a small positive toe change, which can affect turn-in responsiveness and track width. Use it as part of incremental setup changes when tuning roll center, steering feel, or balance on carpet or asphalt touring circuits. Always test changes one at a time and record results to assess handling differences.
