Tamiya 15427 JR Mass Damper Square 6x6x32mm Racing Tune Weight  [15427]

What the Tamiya 15427 JR Mass Damper Square Does

The Tamiya 15427 JR Mass Damper Square is a tuning weight that helps control dynamic movement in Mini 4WD cars. Its square section is simple to fit and gives clear feedback when you alter placement during setup.

Track Behaviour and Role

Mass dampers smooth sudden shifts in attitude by adding focused inertia, so the car resists pitching under acceleration or on landing. This helps maintain traction and keeps the chassis settled through fast sequences.

Which Cars and When to Use It

Compatible with many Mini 4WD platforms, the Tamiya 15427 is handy when you need added ballast without bulky hardware. Use it to tune transitions, reduce snatch on high speed sections, or stabilise after jumps.
