Performance Chassis Plate for BD9 2019

The aluminum main chassis plate sold as Yokomo B9-00219AA is an aftermarket replacement for the BD9 2019 platform. It locates key mounting positions for suspension, drivetrain components, and electronics on compatible BD9 variants.

Machined aluminum construction increases chassis rigidity relative to the original composite, which changes the car's dynamic reactions. After fitting, re-evaluate shock geometry, ride height and check the clearance envelope for the servo, ESC and motor to avoid contact.

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 tuning steps should I start with after installation?

Begin by checking ride height and damper droop, then test with small changes to anti-roll and shock oil to dial in turn-in and mid-corner balance for the stiffer chassis.

Does the chassis weight affect balance?

Aluminum tends to add mass to the centre section, which can lower the polar moment and influence rotation; account for this when adjusting corner weights and battery position.

Can it be used with other aftermarket upgrades?

Yes, it is compatible with many BD9 upgrades, but verify clearances and mounting alignment when combining parts from different manufacturers.

How should I validate changes on track?

Make one setup change at a time, log lap times and handling notes, and run repeatable tests to understand how the stiffer chassis affects corner entry and exit behaviour.
