Carbon Wide Rear Multi Roller Plate for M/AR Chassis M4WD-14 by 3Racing  [M4WD-14]

Carbon wide rear plate details and tuning advice

This aftermarket carbon wide rear multi roller plate suits Mini 4WD builders working with M or AR chassis. It increases the rear footprint and supplies numerous drilled mounting positions so you can experiment with roller layouts without changing the main stay. The focus here is on material properties and the hole matrix rather than installation steps.

The rigid carbon reduces unwanted flex that is common with plastic stays, keeping rear mounting points stable under side loads. That rigidity affects cornering and rebound, so racers should expect a firmer rear platform and balance that with roller geometry adjustments and height tuning.

Check that your M or AR chassis accepts this type of rear stay replacement before buying. Ensure screw spacing and roller clearance will work with your setup; some tuners drill or countersink selected holes to fit specific screw types or custom roller mounts. This is primarily a structural replacement rather than a complete assembly.
