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

Rear topdeck solution for XRAY T4 FWD

This Arrowmax AM-920014 2.0mm rear topdeck is an RC replacement plate engineered for XRAY T4 front-wheel-drive chassis to modify rear rigidity and overall balance. It functions as a tuning component to help adjust how the rear reacts under cornering and during traction changeovers.

Compatibility is specific to XRAY T4 FWD configurations listed in the product title and requires the standard T4 chassis mounting points and common hex screws used on that platform. Installing is straightforward for hands-on hobbyists: remove the current plate, seat the 2.0mm topdeck on the designated posts and fasten evenly to avoid twisting the plate.

Using this topdeck increases rear stiffness compared with the stock plate, which typically affects corner entry and mid-corner stability while leaving suspension geometry unchanged. Pair the plate with roll centre, damper and anti-roll bar adjustments to fine-tune handling, and inspect mounting fasteners and contact surfaces regularly.
