Refine Handling with Tamiya 15428 - JR Mass Damper Square for Mini 4WD Cars

The Tamiya 15428 JR Mass Damper Square is a practical tuning part for racers who want sharper control over attitude during fast sections. Its square cross-section delivers predictable damping of pitch and bounce, helping keep velocity through tricky sequences. Installation can be done on the stays or attached straight to the chassis to suit different chassis layouts.

Using a mass damper is a straightforward way to reduce unwanted motion and stabilise the car for cleaner lines. This Tamiya unit comes in at 15.8 grams and needs common fixings such as screws, 2mm nuts, lock nuts and washers to secure it properly.

How does the square shape change behaviour compared to round dampers?

The square section gives a different center of mass distribution and contact profile, which can result in a more consistent damping effect under pitch than some round designs.

Is special tooling required to fit the Tamiya 15428?

No specialised tools are needed beyond standard hobby screwdrivers and pliers; just ensure the chosen screw length clears any nearby parts and the damper mounts securely.

Will adding this damper slow my car down?

Any added mass can affect peak speed slightly, but the stability gains usually translate to faster, more consistent lap times by reducing mistakes caused by pitch and bounce.

Where should I start when tuning placement?

Begin by mounting the damper near the car centreline and test entry and exit behaviour; move it forward or rearward in small steps to see how it changes rotation and landing attitude.
