XRAY T4 Graphite Upper Deck 1.6MM Tuning Plate - Arrowmax AM-T4-301061  [AM-T4-301061]

Upper deck upgrade for T4'20

The Arrowmax AM-T4-301061 1.6MM graphite upper deck is a replacement plate made for XRAY T4 touring car chassis. It connects to the factory mounting points and upper suspension pickups, acting as a tuning option to alter chassis stiffness and balance for improved on-track behaviour.

Fitting is straightforward: remove the stock upper deck and mount the Arrowmax plate onto the original chassis bosses using the existing hardware. When used with compatible T4 variants no chassis drilling or trimming is normally needed. The plate keeps the standard layout for upper suspension links and accessory mounts so swapping is familiar to anyone experienced with T4 maintenance.

As a tuning part the 1.6MM graphite deck increases torsional rigidity and shifts how flex is distributed through the chassis. Drivers can combine this plate with suspension and anti-roll bar changes to refine mid-corner bite and transient response. It is offered as an option for racers and hobbyists who want to change base stiffness without replacing 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.
