XRAY T4 Rear Topdeck 2.0mm Performance Plate - Arrowmax AM-920014  [AM-920014]

Rear topdeck upgrade kit for XRAY T4 FWD

The Arrowmax AM-920014 2.0mm rear topdeck is a replacement tuning plate for XRAY T4 front-wheel-drive chassis, intended to alter rear stiffness and fine-tune balance. It is used as a setup tool to influence rear behaviour during corner entry and traction transitions on the circuit.

Fitment is aimed at XRAY T4 FWD chassis as named and uses the standard T4 mounting pattern and typical hex screws. Installation is simple for those comfortable with chassis work: remove the stock plate, align the 2.0mm topdeck to the posts, and torque screws evenly to avoid bending the plate.

When installed, expect increased rear stiffness compared to stock, which commonly sharpens turn-in and adjusts mid-corner traction rather than modifying suspension geometry. Combine the topdeck change with shock and anti-roll bar tuning to get the handling you want, and routinely check fastener torque and mating surface flatness.
