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

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

The Tamiya Mini 4WD Roller Stopper in black, 3RACING M4WD-11/BK, is aimed at racers who want steadier behaviour through corners. The part reduces unwanted lateral motion of the rollers so your car stays engaged with the racing line and reacts more predictably to steering inputs and bumps.

Fitment and Role

This stopper fits a range of Tamiya Mini 4WD chassis, including MS, MA and AR platforms. It controls excessive roller travel that can cause instability on tight turns, helping maintain consistent contact and lowering the risk of the car climbing the guardrail on abrupt curves.

Racing Benefits and Practical Tips

On twisty layouts the Roller Stopper helps drivers hold a cleaner line and produce repeatable lap times. It is particularly helpful when combined with tuned rollers and a balanced weight setup to keep the chassis stable through rapid sequences.
