This narrow graphite upper brace is an RC tuning accessory for the 1/12 Yokomo R12c3.1 chassis and is compatible with friction-type roll dampers. It installs at the upper brace point to change chassis stiffness and to match the R12c3.1 layout without interfering with existing components.
The part uses the same upper brace mounting points on the R12c3.1 chassis and is designed for the same hardware pattern as the stock brace, so compatible R12c3.1 builds should not require chassis modification to fit this unit.
From a setup perspective, the graphite narrow upper brace influences how loads are routed between links and dampers, creating a different flex response that can be combined with friction roll dampers to refine roll behaviour and balance for 1/12 competition use.
