XRAY T4 MID Upper Plate 2.0mm Hard Type 2 AM-910015 by Arrowmax  [AM-910015]

Intro to the T4 MID topdeck

The Arrowmax AM-910015 topdeck is an aftermarket 2.0mm Hard Type 2 upper plate made for XRAY T4 MID configurations. It joins the front and rear suspension mount areas and its increased stiffness helps limit chassis deformation, improving steering accuracy and roll control when tuning for grip.

This item is targeted at the XRAY T4 MID chassis as a model-level tuning piece. Fitting requires removal of the original topdeck and transfer of the stock mounting hardware to keep factory geometry. Confirm the MID layout on your T4 before installing to avoid fitment issues.

This topdeck is a sensible next step if you need a firmer upper plate to cut flex on XRAY T4 MID cars; its effect should be judged on-track and balanced with suspension and alignment tweaks.
