The Arrowmax AM-910035 is a rear chassis stiffener developed for the AM Medius MID platform. Supplied as an aftermarket tuning accessory, it provides an additional mounting option to influence rear torsional rigidity without altering the suspension geometry.
Installation is suitable for hobbyists with basic chassis experience; the brace mounts to the Medius MID rear chassis points and utilises the car's standard fastener positions. Always check fit and ensure there is no contact with electronics or drivetrain parts during suspension travel prior to final assembly.
In tuning practice the stiffener acts as a chassis-level adjustment: fitting it increases rear stiffness which can reduce rear squat and sharpen turn-in by lowering chassis flex, while removing it or fitting a lighter variant increases rear compliance for more traction on low-grip surfaces. Apply small changes and evaluate on the track to understand the handling effects.
Use this part as a tuning option for Medius MID cars to fine-tune rear behaviour; confirm fitment on your particular chassis build before competitive use.
