Tamiya Mini 4WD Black Roller Stopper 3RACING M4WD-11/BK Precision Fit  [M4WD-11/BK]

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

The Tamiya Mini 4WD Roller Stopper in black, 3RACING M4WD-11/BK, is intended to sharpen handling by reducing unwanted lateral roller travel. This stabiliser keeps the rollers tracking the same line through corners, helping drivers maintain control during rapid direction changes.

Design Intent and Fit

Designed to suit common Tamiya Mini 4WD chassis like MS, MA and AR, the stopper restricts lateral motion that can cause instability on tight corners. By holding roller movement within a controlled range, it lowers the chances of the car lifting or snagging on track barriers.

Why Racers Add a Stopper

For competitive layouts with quick transitions, the Roller Stopper helps preserve momentum and improves predictability when entering and exiting bends. It is a useful addition for racers focusing on consistent lap times and reliable car setup.
