This anodized light blue rear hub carrier is an aftermarket hop-up for the Tamiya M03M platform, engineered to establish a consistent 2 degree rear toe. It is intended for competitive setup work where repeatable rear geometry is critical to lap-to-lap consistency.
Compatibility is limited to the M03M family as indicated in the part name. The alloy construction alters stiffness and long term wear characteristics relative to the original plastic carrier, which can benefit repeatable handling and tuning precision during race setups.
Installation aligns with standard rear carrier replacement: remove the rear wheel and hub assembly, install the carrier, then reassemble and verify toe and wheel alignment. After fitting, run clearance and roll checks before full running and include routine inspections during race events.
