XRAY T4'20 Upper Deck 1.6MM Graphite by Arrowmax AM-T4-301061  [AM-T4-301061]

Upper deck for T4'20

This Arrowmax AM-T4-301061 graphite upper deck is an RC-scale replacement upper plate intended for use on XRAY T4 touring car chassis. It serves as a structural component that interfaces with the existing chassis mounts and upper suspension pickups, and is intended to be used as a tuning option to alter chassis stiffness and balance.

Installation is performed by removing the stock upper deck and fitting the Arrowmax plate to the factory mounting points using the original hardware. No modification to the chassis should be required when used with compatible T4 variants. The deck retains the layout for upper suspension links and common accessory mounting so replacement is straightforward for users familiar with T4 maintenance.

As a tuning element the 1.6MM graphite plate affects torsional rigidity and the distribution of flex across the chassis. Drivers can use it to fine tune mid-corner feel and transient response in combination with suspension and anti-roll adjustments. The part is presented as an option for racers and hobbyists who want to vary the base stiffness without changing major chassis components.

Use this upper deck as a direct replacement or tuning hop-up on XRAY T4 cars to explore different chassis stiffness setups while keeping the original mounting scheme intact.
