Arrowmax AM-920045 AM Medius FWD Bumper Foam  [AM-920045]

Front bumper foam for Medius FWD

This Arrowmax AM-920045 AM Medius FWD bumper foam is an RC-scale front bumper insert designed for the AM Medius FWD application. It serves as a replaceable foam element that sits inside the front bumper shell to absorb low-speed impacts and reduce chassis shock transmission.

Materials and function are straightforward: the component is foam-based and intended to moderate front-end impact energy, helping protect the body shell and reducing sudden feedback to suspension and steering components. It is a tuning element rather than an electronic or mechanical part, used to fine-tune front compliance and feel.

Installation is simple and chassis-focused: remove the bumper shell, position the foam inside the bumper cavity so it aligns with the body contact points, then refit the bumper using the vehicle's original fasteners. Minor trimming can be done for a snug fit if the bumper shell variant requires it, but no modification to suspension or mounting points is necessary.

Tuning tips: changing foam position or stacking thin pads can increase front firmness or softness, which affects bite under braking and initial turn-in. Use incremental adjustments and test on your typical surface to evaluate changes in steering feedback and impact mitigation.
