This 12mm aluminium adaptor is manufactured as Version 2 to fit the Tamiya TA05 range including TA05, TA05-IFS, TA05-R and TRF-416, introducing a controlled +1 degree toe change. It is a compact offset component designed to alter contact patch geometry without replacing hub housings or wheel hexes.
Fitment follows standard touring car procedures: remove wheel and existing hex or adaptor, mount the 12mm adaptor to the axle/hex interface, then secure using the original wheel nut or retaining device. Ensure correct hex driver use, full thread engagement and perform flat-surface alignment checks before track use.
From a setup perspective, this adaptor modifies track width and adds a slight positive toe that can refine initial turn-in and mid-corner balance. Use it as a measured tuning step, pairing with incremental suspension or steering adjustments and documenting lap data to quantify handling changes.
