The Tamiya Mini 4WD roller stopper in light blue from 3Racing M4WD-11/LB is a compact upgrade that helps control roller movement and delivers steadier handling. It is valued by racers who run technical track layouts.
This stopper is compatible with the common Mini 4WD roller configuration and typically installs with basic tools. The light blue finish offers a neat visual touch without altering function.
By curbing side-to-side roller play, the stopper supports cleaner cornering lines and reduces instances of rollers disengaging on tight sequences, aiding consistency over multiple heats.
