The Arrowmax AM-T4-301060-V2 is a 2.25mm graphite top deck built for the XRAY T4'20 chassis. As a replacement plate it changes the car's stiffness and offers a consistent surface for mounting electronics and upgrades.
Graphite construction targets drivers and setup-minded hobbyists who use chassis flex to tune handling. The plate uses the T4'20's existing upper-deck mounting holes and typically swaps in place of the stock part without special hardware.
Consider the deck part of your tuning toolkit: a stiffer top plate moves flex distribution front to rear, so pair changes with tyre choice and damper settings to dial in lap time or drivability.
Use track testing to verify the effects of the deck, then tweak suspension and tyre setup to match the new chassis behaviour.
