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

M4WD-13 carbon rear wide stay for Tamiya Mini 4WD models

This wide rear multi roller plate is a carbon-fibre upgrade for 1/32 Tamiya Mini 4WD cars. It is profiled to accept wider roller positions and is commonly fitted to Super-II and MA series chassis. The following sections detail build notes, compatibility and collector advice.

Built from a single carbon layer with strategically placed cutouts, the plate reduces weight while preserving stiffness at fastener and roller locations. It adds multiple rear roller mounting options compared with standard plastic stays, allowing different roller geometries without replacing the main chassis. As a structural component, verify body and rear stabiliser clearance before final installation.

Compatibility is aimed at common Mini 4WD rear layouts used on performance chassis. Fitment may require M3 or M2.6 fasteners depending on roller assemblies; always check hole spacing and use spacer washers where required. This part changes roller layout only and does not alter drivetrain components.

For collectors, observe that carbon ages and handles impacts differently to plastic: superficial marks are usually cosmetic but delamination or broken bosses mean the part has suffered stress. Confirm flatness and mounting hole condition before adding to a display chassis.
