Yokomo B9-BW30A Center Balance Weight (30g)  [B9-BW30A]

Center balance weight for BD9

The Yokomo B9-BW30A is a 30g center balance weight designed for BD9-style touring chassis. Fitted at the central section of the chassis, it provides a measured increase in mass without changing the lateral balance of the car, allowing for subtle tuning of weight distribution during setup sessions.

Compatibility is limited to the specified MRTC-BD919 and MRTC-BD919S chassis listed by the manufacturer, installed in the midline area to keep suspension and steering behavior consistent while altering overall inertia.

Use this 30g center weight when you need a compact way to adjust front-to-rear inertia without altering corner balance, keeping tuning predictable across different track conditions.
