Yokomo BD9 Chassis Magnesium Stiff Plate Upgrade - Arrowmax AM-900004  [AM-900004]

Magnesium stiffening plate for BD9 chassis

This Arrowmax accessory is a magnesium stiff plate designed for use with the Yokomo BD9 1/10 touring car chassis. The component is focused on raising overall chassis rigidity to help you get a steadier reaction when changing suspension setup or redistributing weight. The paragraphs below outline where this plate fits into a typical tuning sequence, what to check during installation, and the handling shifts you can expect.

Compatibility and purpose: the plate is made for the Yokomo BD9 platform and acts as a direct replacement or upgraded chassis section depending on your BD9 variant, helping to limit chassis twist and sharpen steering feedback. Installation notes: it uses the BD9's existing mounting points and hardware, so plan to reuse original screws and spacers; check alignment at every mount before final torque. Tuning notes: added chassis stiffness normally brings quicker initial turn and steadier mid-corner traction, so adjust shock damping and anti-roll bar stiffness to restore balance.

Compatibility

Built for the Yokomo BD9 series chassis; confirm which BD9 variant you own before fitting to guarantee correct mounting orientation and hardware compatibility.

Practical and neutral in tone, the Arrowmax AM-900004 magnesium plate is a straightforward tuning upgrade for drivers wanting to cut chassis flex and achieve more consistent handling on Yokomo BD9 touring cars.
