The Yokomo Y2-303RBA is an optional aluminum brace created for the 2WD YD-2 drift chassis. It supplies a reinforced rear mounting point and includes a flat top section designed to accept a 30mm square cooling fan.
Adding a separately sourced 30mm fan to the brace provides active cooling for a rear-mounted motor without relocating the motor or modifying primary chassis components. The unit is offered without the fan and is intended as an upgrade to help manage motor heat while supporting setup changes that affect rear handling.
Fitment involves aligning the brace with the existing rear mounts on the YD-2 and fastening it with the matching factory hardware; no major chassis modification is required. The Y2-303RBA acts as a structural and thermal support component rather than a part that alters drive configuration.
For YD-2 owners wanting a compact cooling mount and a firmer rear anchor point, the Y2-303RBA provides straightforward fitment and thermal support during setup and track sessions.
