Tamiya 3RACING M4WD-11/BK Roller Stopper Racing Spec  [M4WD-11/BK]

Racing Spec Roller Stopper for Tamiya Mini 4WD - 3RACING M4WD-11/BK

The Tamiya Mini 4WD Roller Stopper in black, 3RACING M4WD-11/BK, is a compact component aimed at improving chassis stability under high lateral loads. It limits excessive roller displacement to preserve tyre and roller alignment through fast, technical sections of the track.

Engineering Purpose and Chassis Fit

Optimised for common Tamiya platforms such as MS, MA and AR, the stopper reduces lateral articulation that can provoke derailment on sharp turns. Correct installation maintains predictable roll paths and supports consistent tuning of suspension and roll geometry.

Race Setup Guidance

In a competitive setup the Roller Stopper contributes to repeatable lap performance by narrowing variables caused by roller movement. Use it alongside tuned rollers, tuned weight distribution and careful clearance checks to extract stable cornering without sacrificing roll efficiency.
