This RC-scale rear diffuser is produced for the DP-YD2 platform and comes as a pair of wide and narrow profiles to permit chassis-level tuning on scale drift and touring setups. It is intended to match the DP-YD2 body mount layout and not to imply fitment on real vehicles.
Functionally the diffuser is a setup tool: the wide profile enlarges the diffuser outline to change rear body airflow interaction compared with the narrow profile, and swapping between them is a practical way to alter rear traction, yaw response, and body clearance according to track conditions.
Fitment uses the DP-YD2 rear body mounts and follows normal RC assembly procedures; inspect body alignment and wheel-to-body clearance after switching diffuser width to prevent contact during suspension travel. Use moderate thread-lock on metal fasteners when needed for durable fitment.
Treat the two parts as a compact tuning set for stepwise adjustments to rear behaviour during practice and setup sessions.
