Viper 990e R (SER904008) Carbon Fibre Chassis Plate - SER904230 by Serpent  [SER904230]

Replacement carbon mainplate for Viper 990e R

The Serpent SER904230 carbon chassis plate provides a direct replacement option for the Viper 990e R (SER904008). Manufactured in carbon fibre, the plate replaces the stock centre section to modify torsional rigidity while keeping original mounting points intact.

Installation requires removing bodywork and electronics as necessary to access the mount points, moving over servos, ESC and motor mounts, and securing the new plate with the vehicle's own screws. Check that screw lengths match the insert depth to prevent compressing the laminate or stripping threads.

Switching to the SER904230 alters the car's transient and steady-state behavior. Increased stiffness tends to reduce chassis flex and produce a more precise steering sensation; counterbalance these changes with adjustments to damping, spring rates and tyre compound to find the desired traction balance.

Care recommendations include keeping mounting holes clear, washing grit from between lamination layers, and regularly checking that metal inserts are fully seated. If any unusual play appears, remove the plate and inspect inserts and fasteners before further use.

Intended for enthusiasts who want a straightforward carbon replacement on the Viper 990e R to stiffen the chassis and tune handling traits through setup changes and component transfer.
