GPM PMIF0612F/R sinkage rims are precision-moulded plastic components designed to align with Kyosho Mini Inferno hub geometry and tyre bead dimensions. The sinkage geometry supports consistent tyre load distribution and repeatable seating, which aids steering predictability and lap-to-lap consistency. The construction focuses on dimensional accuracy and serviceable durability while maintaining low rotating mass, making these rims suitable for tuners seeking reliable fit and improved on-track behaviour.
