For precise setup adjustments the Serpent 903759 Brass Chassis Weight offers a compact 14 gram option specifically for the S989. It helps centre mass lower for improved stability during fast sections and tighter turns.
Brass provides consistent mass and resists wear, so this weight delivers lasting performance. Properly applied ballast improves cornering balance and lowers the chance of rollovers when driving aggressively.
Manufactured to suit the Serpent S989 mounting layout, this chassis weight installs cleanly without modifications. The precise fit speeds up setup changes so you can concentrate on suspension and tyre choices.
