Centered ballast for BD9 setups

The Yokomo B9-BW40A is a 40g centre balance weight offered as an upgrade accessory for BD9-type cars. Fitted centrally, it helps control the car's pitch and roll tendencies while preserving the overall balance across the chassis.

Intended for BD9-compatible frames, the weight offers a neat method to introduce central ballast during tuning sessions on electric touring vehicles. Mounting at the centre keeps the effect focused on the vehicle's core mass distribution rather than per-corner tweaks.

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.

Is this weight robust for frequent track use?

The specification does not list material details, so treat it as a functional ballast; inspect mounting points regularly for wear.

Will it corrode if exposed to moisture?

Material is unspecified in the provided data; avoid prolonged exposure to moisture and dry components after wet runs to reduce corrosion risk.

Can I combine this with corner weights?

Yes. Central ballast complements corner-specific weights and is useful when you want to alter global pitch and roll without changing corner balance directly.

How often should I check the fitment?

Check the fitment before each session and after any contact incidents to ensure screws and seating remain secure.
