The WH-15/R/BL rear assemblies are supplied as four matched tyre-and-rim units intended for rear fitment on the TAMIYA DF03 chassis. Units are prepared for straightforward replacement and consistent mounting geometry across all four corners.
Intended application: these assemblies are replacement parts and light tuning components that alter rear track and rotational mass without modifying drivetrain layout. They are suitable for restoring factory geometry, swapping between tyre compounds, or presenting a scale-accurate wheel option for events.
Service procedure: remove the rear wheel assemblies using the standard DF03 wheel-retention process, fit each assembly sequentially, confirm tyre bead seating and secure retention, and verify unobstructed rotation and absence of lateral play. Conduct a static balance check or a short controlled run to validate fitment.
Tuning guidance: wheel mass and width affect unsprung inertia and cornering balance; after installing WH-15/R/BL wheels, re-check rear ride height, toe and camber settings on the DF03 to preserve handling consistency.
