Serpent SER903776 Viper S989 Flex Insert Set - 2 Pieces  [SER903776]

Chassis Tuning Inserts for Viper S989

The Serpent SER903776 Flex Insert is made to suit the Viper S989 GP chassis, giving controlled flex that sharpens handling and steadies the car at speed. These inserts seat cleanly in the S989 chassis slots to deliver a secure fit that helps reduce twitchiness during aggressive driving.

Adjustable Flex for Better Handling

These inserts are a simple way to influence suspension behaviour on the Viper S989 GP. By changing local rigidity you can find a balance between stiffness and compliance, which helps with corner entry, mid corner balance and exit traction across different track surfaces.

Simple Fitment and Quick Changes

Fitting the Serpent inserts requires no specialised tools; slide them into the designated slots in the S989 chassis. That quick installation makes it easy to experiment with setups between practice runs or heats.
