For hobbyists who tweak handling, the Serpent 903618 Aero Bumper Inserts are a worthwhile upgrade. Created for the 977 chassis, they help smooth airflow and contribute to more predictable behaviour at higher speeds.
These inserts help control frontal airflow to reduce drag and improve directional stability. Fabricated from a durable material, they are built to last through practice runs and race weekends.
They integrate cleanly with the 977 chassis, letting you evaluate aerodynamic changes without complex modifications. That makes them practical when testing setup adjustments trackside.
