Viper 990e R Chassis Upgrade Plate (SER904008) - Serpent SER904230  [SER904230]

High-stiffness carbon base for Viper 990e R

The Serpent SER904230 carbon chassis plate is designed as a straight replacement for the Viper 990e R (SER904008). As a structural centrepiece, it swaps directly into the original mounting geometry to modify stiffness and the car's dynamic response.

Installation involves removing bodywork and electronics as required, transferring servos, ESC and motor mounts, and securing the new plate using the existing screws. Confirm insert condition and correct screw lengths to prevent damaging the carbon laminate or metal threads.

Changing to a carbon plate affects how the model reacts to inputs: expect sharper steering and reduced chassis deflection. Rebalance handling using shock tuning, anti-roll adjustments and tyre choices to suit track surface and driving style.

Routine checks include examining mounting holes for wear, cleaning grit from between plies and ensuring inserts remain properly seated. Any abnormal noises or looseness should be investigated and resolved before further running.

This carbon plate suits enthusiasts seeking a direct replacement to change the Viper 990e R's baseline stiffness, with handling benefits realised through careful setup and component transfer.
