For modelers focused on control and consistency, the Serpent 904218 Carbon Vertical Topdeck is engineered for the Viper 990E chassis. Built from high-grade carbon fiber, the topdeck raises torsional rigidity without adding bulk, which helps the car hold its line through fast sections. It is a practical upgrade for competitive drivers and trackday hobbyists alike.
Carbon fiber offers a superior strength-to-weight profile compared with many alloys. Installing this topdeck on a Viper 990E lowers rotating mass and maintains durability, translating into sharper handling and steadier behaviour over bumpy surfaces.
The Serpent 904218 fits the Viper 990E mounting pattern and installs with standard hardware. Make sure mounting screws are secure but not over-torqued, and verify chassis alignment after fitting. Small setup tweaks after installation will help dial in the improved stiffness.
