XRAY T4 Upper Deck 1.6MM Graphite Hop-Up - Arrowmax AM-T4-301061  [AM-T4-301061]

Replacement upper deck for T4'20

The Arrowmax AM-T4-301061 graphite upper deck, 1.6MM thick, is a replacement upper plate made for use on XRAY T4 touring car chassis. It attaches to the factory mounting points and upper suspension pickups and is offered as a tuning component to modify chassis stiffness and balance.

Fitting the plate involves removing the original upper deck and securing the Arrowmax unit to the existing chassis bosses with the stock hardware. Compatible T4 variants generally do not need any chassis modification. The plate keeps the original layout for upper links and accessory mounts so swapping is straightforward for hobbyists familiar with T4 upkeep.

As a tuning item the 1.6MM graphite deck alters torsional rigidity and the way flex moves through the chassis. Pilots can use it with suspension and anti-roll changes to fine tune mid-corner behaviour and transient response. It is intended for racers and keen hobbyists who want to change base stiffness without replacing main chassis elements.

Fit this upper deck as a direct swap or tuning upgrade on XRAY T4 cars to test chassis stiffness variations while preserving original mounting points.
