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

Tuning upper plate for T4'20

This Arrowmax AM-T4-301061 1.6MM graphite upper deck functions as a direct replacement plate for XRAY T4 touring chassis. It mounts to the chassis bosses and upper suspension pickups and is used to alter chassis stiffness and balance as part of setup tuning.

To fit, remove the stock upper deck and position the Arrowmax plate onto the factory mounting points using the original screws. Compatible T4 variants should not require any chassis alteration. The deck retains standard openings for upper links and common accessories so installation is familiar to those who maintain T4 cars.

As a setup component the 1.6MM graphite plate increases torsional rigidity and shifts how flex is distributed across the chassis. It is typically used alongside suspension and anti-roll bar adjustments to refine mid-corner behaviour and transient response. The part is aimed at club racers and enthusiasts seeking incremental stiffness changes without replacing the main chassis.

Use this upper deck as a drop-in tuning hop-up on XRAY T4 platforms to test different stiffness levels while preserving the original chassis mounting pattern.
