The GPM T3010/+3MM Aluminum Hex Adapter is engineered to provide a firmer, more reliable rear wheel interface for the TAMIYA T3-01 DANCING RIDER. Manufactured from high-strength aluminum T6, the adapter reduces hex play and improves hub-to-wheel alignment. The updated 12mm hex profile minimises gaps at the mounting surface while the +3mm width increases rear track for improved lateral stability. Fastening is achieved using the included stainless steel fasteners to maintain consistent clamping force and repeatable fitment.
