Serpent SER903776 Flex Insert Set for S989 - Race Day Kit  [SER903776]

Race Day Chassis Inserts for the Viper S989

The Serpent SER903776 Flex Insert has been produced to match the Viper S989 GP chassis geometry, offering a way to fine tune chassis flex and improve on-track composure. The inserts sit precisely in the S989 mounting points for reliable performance during high speed runs.

Tune Flex to Match Track Conditions

By modifying local chassis stiffness these inserts help control weight transfer and balance, making it easier to adapt the S989 to different grip levels. They are useful for dialing in better rotation and exit traction without changing core suspension parts.

Quick Swap Installation

Fitting is direct and clean, requiring only basic tools to seat the inserts into the S989 chassis slots. That fast swap ability makes them handy when you need to adjust the car between qualifying and mains.
