Yokomo B12-003RSP graphite rear upper deck plate for MRTC and MSR BD11/BD12 platforms  [B12-003RSP]

Graphite rear upper deck plate

This RC-scale graphite plate attaches to the upper area of the rear upper deck to manage ATF movement that contributes to rear roll, and to increase rear section rigidity. Designed as a drop-in chassis accessory, the part shifts how fluid dynamics and flex interact at the back end of compatible touring-style frames, offering a neutral, mechanical way to influence rear roll behaviour.

Installation is straightforward for experienced model technicians: the plate mounts to the rear upper deck using the standard mounting points on the listed chassis. No special tools beyond common hex drivers are required, and reuse of existing fasteners is typical when replacing or upgrading the original plate. Confirm fitment against the chassis reference list before fitting.

Tuning role: this plate is intended to alter the ATF flow characteristics that affect rear roll and to stiffen the rear deck to reduce unwanted chassis flex under load. Use it as part of a measured setup change when adjusting rear balance, traction transitions, or when seeking firmer rear-end response without changing suspension geometry.

For RC builders focused on incremental chassis tuning, this graphite upper deck plate offers a compact method to control ATF-influenced rear roll and to raise rear deck stiffness on supported Yokomo touring platforms.
