AM Medius FWD Front Bumper Foam Insert - AM-920045 by Arrowmax  [AM-920045]

Front impact insert for AM Medius FWD

This Arrowmax AM-920045 AM Medius FWD bumper foam is a scale RC front bumper insert made for AM Medius FWD setups. It fits as a replaceable foam block inside the front bumper shell to soak up low-speed knocks and reduce shock passed into the chassis.

Constructed from compact foam, the insert moderates front-end impact energy to help protect the bodyshell and reduce sudden feedback to suspension and steering parts. It functions as a setup/tuning element rather than an electronic or mechanical upgrade, used to adjust front compliance and steering feel.

Fitting is straightforward and chassis-focused: remove the bumper shell, seat the foam inside the bumper cavity so it matches the body contact points, then refit the bumper using the vehicle's original fasteners. Small trimming can be done for a snug fit if that bumper variant needs it; no changes to suspension or mounting points are required.

Tuning tips: moving the foam, shifting its position or stacking thin pads will firm or soften the front end, which changes braking bite and initial turn-in. Make incremental changes and trial them on your usual surface to judge steering feedback and impact control.
