XRAY T4 FWD Topdeck 2.0mm Rear by Arrowmax AM-920014  [AM-920014]

Rear topdeck for XRAY T4 FWD

This 2.0mm rear topdeck is an RC-scale replacement part for XRAY T4 front-wheel-drive chassis focused on changing rear rigidity and balance. It serves as a tuning item to alter how the rear of the car responds under cornering and traction transitions, useful for on-track adjustments where chassis feel and weight transfer are being refined.

Compatibility is limited to XRAY T4 FWD layouts specified in the product name, fitment requires standard T4 chassis mounting points and common hex screws used on the platform. Installation is straightforward for chassis-savvy hobbyists: remove the existing topdeck plate, align the 2.0mm rear topdeck to the designated posts, and fasten evenly to avoid preload or twist.

When tuning, this topdeck is used to increase rear stiffness relative to the stock plate; expect changes in corner entry and mid-corner stability rather than suspension geometry. Pair adjustments with roll center, shock settings, and sway bar choices to dial in the desired handling balance. Regular checks for screw torque and mating surface flatness are advised to maintain consistent behaviour.
