30g centre weight for BD9 setups

The Yokomo B9-BW30A is a 30g centre balance weight created for BD9-style touring chassis. When positioned at the chassis centre it raises total mass while leaving lateral balance largely unchanged, letting you tune how the car carries momentum through corners.

This item is compatible with the specific MRTC-BD919 and MRTC-BD919S chassis noted by the manufacturer, and should be installed on the midline to maintain consistent suspension and steering characteristics while adjusting inertia.

This 30g centre weight offers a compact way to shift front-to-rear inertia without upsetting corner balance, useful for dialing in predictable handling across different track conditions.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How will adding 30g change handling?

Adding mass at the centre increases overall inertia, which can stabilise the car at speed and influence weight transfer under acceleration and braking without large left-right changes.

Should I combine this with other weight changes?

Use this centre weight alongside your existing setup plan; small incremental changes are recommended so you can measure the effect on lap times and balance.

Does placement alter understeer or oversteer?

Because it sits on the centreline, the intention is to affect overall inertia more than corner bias; handling shifts will be subtle and depend on the rest of your setup.

How should I evaluate its effect on lap performance?

Change one variable at a time, run consistent test laps, and compare telemetry or lap times to judge whether the added mass improves stability or slows corner entry and exit.
