Mini 4WD Carbon Wide Front Swing Roller Plate M4WD-50/WO for Super-II MA front stay by 3Racing  [M4WD-50/WO]

Technical overview of the M4WD-50/WO carbon wide swing roller plate

The M4WD-50/WO is a carbon fibre wide front swing roller plate developed as an aftermarket tuning part for Tamiya Mini 4WD front stays. It delivers a pivoting roller mounting solution integrated into a wider plate profile to support aggressive roller positioning and reduced lateral flex compared with standard plastic stays.

Intended for front stay use, the plate is typically fitted to Super-II and MA front stay geometries where the chassis permits the wider footprint. Installation uses standard Mini 4WD fasteners; selective use of thin shims or minor trimming may be required to correct roller toe and clearance. Due to carbon's higher modulus, engineers should apply controlled torque and consider load distribution to avoid localized stress concentrations.

As an aftermarket component, the M4WD-50/WO changes front-stay styling and mechanical behaviour. It is usually supplied without rollers or fixing hardware, so plan parts procurement accordingly and verify bumper and body post clearances before final assembly.
