The 3Racing M4WD-11/LB roller stopper for Tamiya Mini 4WD focuses on reducing roller lateral play to stabilise the running line. It is intended as a tuning component for drivers refining handling on technical circuits.
Fitment aligns with standard Mini 4WD roller fixtures. For competitive setups, consider minor adjustments to roller gap and chassis balance after installation to dial in neutral steering and optimise corner entry.
Use this stopper to manage roller float under heavy lateral loads and maintain consistent contact during sequences of tight corners. Small incremental changes and timed runs help identify the best combination of stopper position and roller choice.
