Tamiya 15501 Slimline Mass Damper Set - Mini 4WD tuning pair  [15501]

Tamiya 15501 Slimline Mass Damper Set details

The Tamiya 15501 Slimline Mass Damper Set is aimed at model racers who need compact ballast to stabilise Mini 4WD cars. Its narrow form factor lets you position weight in tight spots, helping to smooth out reactions during rapid direction changes.

Construction and specs

Both dampers share a 7mm diameter, with the shorter at 5.5mm (1.5g) and the longer at 11.5mm (3g). That combination lets you swap or stack weights for subtle changes in momentum damping without intruding on wheel or chassis clearance.

Where it fits and tweaks

Designed for use with Mini 4WD and Mini 4WD PRO platforms, these dampers may need slight body or chassis trimming to fit certain setups. They are versatile for front, mid or rear placement depending on the handling goal.

On-track tuning tips

Use the lighter damper for slight tuning and the heavier one when you need more suppression of bounce. Test each position over a few laps, noting how the car behaves over jumps, through sweeps and on rough sections to dial in the best configuration.
