Carbon upgrade plate for Viper 990e R (SER904008) - Serpent SER904230  [SER904230]

Stiffness upgrade for Viper 990e R chassis

The Serpent SER904230 carbon chassis plate is an aftermarket carbon mainplate designed for direct fit on the Viper 990e R (SER904008). It replaces the factory centre section to change how the car responds under load while preserving the stock mounting layout.

To install, remove the body and transfer electronics and mounts as required, then secure the new plate using the model's existing hardware. Verify insert integrity and correct screw lengths to avoid compressing the laminate or damaging threaded metal inserts.

Fitting a stiffer carbon plate changes tuning demands: expect quicker steering reaction and reduced mid-corner compliance. Tune spring rates, shock damping and anti-roll settings, and experiment with tyre compounds to regain balance for the desired handling characteristics.

Maintain the plate by checking for insert looseness, clearing debris from between plies, and rechecking fastener torque after a few runs. Address any unusual noises or movement immediately to prevent progressive damage.

Aimed at hobbyists and competitors wanting a straightforward carbon upgrade for the Viper 990e R to deliver firmer handling and sharper response through informed setup changes.
