This aluminium front C-hub is an aftermarket replacement offered by GPM for the TAMIYA DT-03 chassis, delivered as 1pr for direct replacement of the original plastic hubs. It retains DT-03 suspension geometry and mounting points while providing a more robust hub carrier.
Fitting uses conventional DT-03 front hub procedures and the original wheel hub pins and steering knuckle fixings. The aluminium material increases mounting stiffness compared with plastic, which may influence steering feedback and component wear; inspect and reuse original pins or shims when they are serviceable and match manual guidance.
For setup and tuning, this C-hub gives a secure mounting point that improves repeatability in steering response and supports consistent bearing alignment. Use it when replacing worn stock parts or when you want a firmer hub base for setup work.
Opt for this C-hub to keep DT-03 fitment while gaining a sturdier aluminium mounting surface for front-end tuning and maintenance.
