Front bumper ballast explained

The Arrowmax AM-920047 adds 70g of ballast beneath the front bumper of front-wheel-drive RC cars to alter handling characteristics without modifying suspension geometry. It targets predictable changes to balance and steering feel.

Designed as an accessory and not a structural bumper substitute, the AM-920047 mounts under the bumper and nudges the centre of gravity forward. This can help curb snap oversteer or give extra bite to the front tyres depending on tyre choice and setup.

Fitting is straightforward on many chassis, using the bumper's existing mounting points or underside fixings. Because chassis and bumper designs vary, check for interference with steering linkages and body clearance before final tightening.

Specifications

  • Item: AM Medius FWD Bumper Weight 70g Bottom
  • Material: Not specified by manufacturer
  • Model Number: AM-920047
  • Compatibility: Designed for front bumper underside use on FWD RC chassis

For racers and hobbyists after measured front ballast, the AM-920047 offers a neat 70g option to tweak balance; always verify fitment on your FWD chassis to avoid rubbing or contact at full travel.

Do I need to change my tyres after fitting this weight?

You may find front tyre behaviour changes with added ballast. If grip increases or turn-in alters, consider tyre compound or pressure adjustments to rebalance handling.

How secure should the weight be mounted for racing?

Use the original bumper fasteners where possible and ensure all bolts are tight. For competition, a small amount of threadlocker can help prevent loosening under load.

Will this affect battery placement or electronics?

Because the weight sits low and forward, it can change balance slightly; check that batteries and servo linkages still clear the body and that wiring is not strained after fitting.

Can I stack other weights with the AM-920047?

Yes, small additional weights can be combined, but make small incremental changes and test on-track to understand how each addition shifts handling.

Is the AM-920047 suitable for street or drift setups?

It is primarily a tuning part to adjust front bias. In drift setups it may alter snap and entry behaviour; for street setups it can improve turn-in. Trial and adjust based on driving style.
