This 1.2mm steel chassis plate is a direct replacement manufactured from Hudy Spring Steel for the XB4 2026 platform. Its increased mass brings the vehicle's center of gravity down, improving straight-line stability and delivering more consistent behaviour across varying track surfaces without altering the car's core geometry.
On medium- to high-traction layouts the additional weight helps reduce traction-roll during mid-corner weight transfer, keeping the car settled through transitions. The spring steel construction offers toughness for frequent running while producing the handling traits associated with steel chassis plates.
Fitment is direct to the specified chassis code and does not call for other hardware changes; keep existing suspension and differential settings and verify handling with a short test lap before extended use.
Select this chassis when you want a durable, lower-CG steel plate for XB4 2026 setups on medium to high grip surfaces; retain original suspension geometry unless on-track testing indicates small tweaks are needed.
