Tamiya Mini 4WD Super-II MA Wide Rear Carbon Roller Plate M4WD-13 by 3Racing  [M4WD-13]

M4WD-13 single-piece carbon wide rear roller stay for Tamiya Mini 4WD

This carbon rear roller stay suits 1/32 Tamiya Mini 4WD models and is shaped to allow broader rear roller placement. It is popular with tuners using Super-II and MA performance chassis. The section below outlines build considerations, fitment tips and display notes for hobbyists.

Manufactured from a single sheet of carbon with lightening cutouts, the stay trims mass while retaining stiffness at the screw bosses. It offers extra rear roller mounting rows compared with OEM plastic stays so you can experiment with different roller setups without swapping the main chassis. Verify rear stabiliser and body mount clearance before final assembly.

The plate is compatible with common Mini 4WD rear layouts. Installation may require M3 or M2.6 fasteners and spacer washers depending on your roller assemblies; check hole centres against your current stay. This component modifies roller geometry only and does not change motor or gearbox placement.

For those collecting display builds, carbon finishes age differently to plastic parts: surface scuffs are common but split fibres or damaged bosses signal impact damage. Confirm flatness and hole condition on pre-owned items to ensure correct fit and presentation.
