The Tamiya Mini 4WD Roller Stopper in red, produced by 3Racing, is intended as a stability aid to reduce chassis roll during aggressive cornering. It is compatible with a range of Tamiya Mini 4WD chassis and supports precise handling adjustments.
Engineered to sit within common mounting layouts, this stopper limits lateral tipping and helps retain optimal line through rapid direction changes. It is a straightforward addition for racers seeking measured improvements in corner control.
Use the stopper as part of an overall tuning approach, pairing it with wheel, roller and weight adjustments to refine balance. Its effect is to stabilise the chassis under load, aiding consistent lap times on technical courses.
