The Arrowmax AM-T4-301060-V2 is a 2.25mm graphite upper plate manufactured for the XRAY T4'20 chassis. It serves as a direct replacement to change chassis stiffness and to provide stable mounting for common electronics and upgrades.
Made from graphite, this upper plate suits racers and setup-focused hobbyists who tune flex to influence steering and traction. It mounts to the T4'20 using the stock upper-deck points and normally does not require special fasteners.
Remember to treat the upper deck as a tuning variable: a firmer plate shifts front/rear flex balance, so test changes together with tyre and suspension adjustments to achieve the handling you want.
Use incremental testing on-track to evaluate changes, then fine-tune suspension and tyre choices to complement the revised chassis characteristics.
