This machined aluminium suspension mount is produced as an aftermarket tuning component for the TAMIYA chassis listed in the title, specifically TRF 415 and TRF-416. The unit replaces the original polymer mount to increase local stiffness at the suspension pivot, improving consistency under repeated load cycles.
Confirmed compatibility is limited to the named chassis codes: TRF 415, TRF-416, FF03 and TA-05IFS. Fitment should be validated against the chassis parts diagram to ensure identical screw patterns and pick-up geometry.
Installation: the mount interfaces with existing suspension pick-up hardware and generally requires standard hobby hand tools. Pay attention to thread engagement and recommended torque to avoid stripping. Verify orientation and hardware sequence from the chassis documentation before final tightening.
Setup guidance: replacing the stock mount with aluminium raises pivot stiffness and can sharpen steering response while changing roll behaviour. When using this part in a race setup, reassess anti-roll balance, spring rates and damper tuning to optimise traction and turn-in characteristics.
