Refine BD9 handling with a 50g central balance unit

The Yokomo B9-BW50A Center Balance Weight is a compact tuning item for BD9 chassis owners. Weighing 50g, it enables careful adjustment of the car's centre of gravity to improve overall steadiness without altering core components. It is useful for drivers seeking a calmer car through chicanes and complex corner sequences.

Effects of central weight on corner behaviour

Placing mass close to the centre alters the chassis roll and yaw characteristics, helping reduce abrupt weight shifts. The Yokomo B9-BW50A makes these adjustments easy to test so you can fine tune neutral balance and steering response for different track sections.
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.

What chassis parts should I check before fitting this weight?

Ensure the central mounting area is free of debris and that existing screws and brackets are in good condition. Fit the weight to the designated centre points on BD9 layouts like MRTC-BD919 and MRTC-BD919S.

Will this help on low-grip surfaces?

On lower grip surfaces, centralising weight can stabilise rotation and improve predictability, but tyre choice and suspension tuning remain the primary factors for traction.

Can I combine this with other ballast options?

Yes. Use the Yokomo B9-BW50A together with small wheel or chassis ballast to fine tune front-rear bias. Change one variable at a time and record handling changes to achieve the desired setup.
