The Arrowmax AM-910016 Medius chassis is a 7075 aluminium replacement chassis plate made for XRAY T4 MID touring cars. It is a direct-fit component designed to increase chassis stiffness and influence handling balance without changing OEM parts.
Swapping to a 2.0mm 7075 plate is primarily a setup move: the increased rigidity alters responses under acceleration, cornering and braking. You will usually address those changes by tuning ride height, spring and damper rates rather than altering mechanical geometry.
Fitting follows the standard T4 MID chassis removal and refit procedure. Use the correct torque values for mounting hardware, check clearances around the servo, ESC and battery, and confirm there is no contact with drivetrain or body mounts before you run the car.
Fit this plate when you want a firmer baseline for setup work; validate fit and repeatability, and make measured suspension adjustments to tune handling predictably.
