Centreline mass plate for BD9 touring chassis

The Yokomo B9-BW30A is a 30g centre balance weight suited to BD9-style touring chassis. Installed on the central chassis area, it delivers a precise mass increase while preserving left-right balance, useful for refining longitudinal weight distribution during setup.

It is specified for use with MRTC-BD919 and MRTC-BD919S chassis as listed by the manufacturer, and should be fitted on the chassis midline to keep suspension and steering behaviour consistent while changing overall inertia.

Specifications

  • Item Center balance weight
  • Material Not specified
  • Model Number B9-BW30A

Choose this 30g centre weight when you need a compact option to tune front-to-rear inertia without disturbing corner balance, aiding predictable handling across different circuits.
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.

Will this fit different BD9 variants?

It is listed for MRTC-BD919 and MRTC-BD919S. Other BD9 variants may require checking mounting points for fitment compatibility.

Are chassis modifications needed to install it?

No special modifications are indicated; fit to the chassis manufacturer's mounting locations. If your chassis has custom parts, verify alignment before final tightening.

Does battery position affect the outcome?

Battery placement interacts with centre mass changes; consider battery position when judging the weight's effect on balance and adjust as required for desired handling.

Any notes on steering feel after fitting?

Because the weight is central it is intended to leave left-right corner bias largely unchanged, but you may notice subtle differences in turn-in and mid-corner stability to be balanced with spring and damper settings.
