Fine Tune Your BD9 with the Yokomo B9-118GPA

The Yokomo B9-118GPA Aluminum Battery Guide Post is built to integrate cleanly with the BD9 chassis. It gives club racers a reliable method to adjust how the car bends and reacts, helping to balance turn-in and mid-corner behaviour.

Simple Spacer-Based Flex Control

Attach the guide post to the upper deck and use a spacer to change chassis compliance. This makes it easy to test different flex settings without major disassembly, useful when comparing setups between sessions.

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.

Which spacer thickness should I try first?

Start with a medium spacer and test a few laps. If the car understeers, reduce flex by removing a spacer; if it oversteers, add a spacer to increase flex.

Will this work with foam or rubber tyres?

Yes, the guide post adjusts chassis behaviour regardless of tyre type, but tyre grip levels will influence which spacer setup performs best.

Do I need special tools to fit it?

No special tools are required. Common hex drivers and a small wrench are usually enough to secure the post and spacers.

Is it worth upgrading from plastic posts?

Aluminium posts offer more consistent flex behaviour and greater durability, making them a good upgrade for regular racers who change setups often.
