Serpent SER411454 Brass ESC Holder - S120 PRO Balance Upgrade  [SER411454]

Weight-Tuned ESC Holder for the S120 PRO

The Serpent SER411454 Brass ESC Holder is crafted to optimise the mass distribution on your S120 PRO chassis. Using brass as the material gives predictable weight bias that helps the car sit flatter through bends.

Better Cornering on High Grip Surfaces

Placing weight low and central improves tyre contact patch behaviour on high traction circuits, which in turn reduces mid-corner understeer and stabilises the car when applying power.

Plug-In Fitment for the S120 PRO

This holder installs into the standard S120 PRO layout with minimal fuss and holds its shape under race loads, so it will not loosen or rattle during hot laps.

If you are tuning an S120 PRO for more consistent mid-corner balance and cleaner exits, the Serpent SER411454 provides a simple mechanical fix to help lap times.
