The Tamiya 15517 Short Mass Damper Block is a small but effective upgrade for Mini 4WD builders who want more control over vehicle balance. These short damper blocks help lower the centre of gravity to reduce body roll and improve composure at speed.
These damper blocks are made to work with MA, FM-A and AR chassis variants, allowing simple placement to fine tune front or rear weight bias. By shifting the mass damper position you can dial in straight line stability or better cornering grip depending on track layout.
In race setups the short mass damper gives a quick way to test weight distribution changes without major modification. Try small incremental moves and test on practise laps to find the best compromise between stability and responsiveness.
