MRTC / MSR BD11/BD12 Graphite Rear Upper Deck Plate - Yokomo B12-003RSP  [B12-003RSP]

Rear upper deck graphite control plate

This RC-grade graphite plate secures to the upper portion of the rear deck to influence ATF movement that contributes to rear roll, while also increasing stiffness across the rear section. Engineered as a drop-in upgrade, the part alters the interaction between fluid dynamics and chassis flex at the back end of compatible touring frames, giving a neutral, mechanical method to adjust rear roll behavior.

Installation is straightforward for experienced model builders: the plate mounts to the rear upper deck using the chassis standard mounting points. No special tools beyond common hex drivers are required, and reuse of existing fasteners is common when replacing the original plate. Always confirm fitment against the chassis compatibility list before installing.

Tuning purpose: this plate modifies ATF flow characteristics that affect rear roll while stiffening the rear deck to reduce unwanted flex under load. Fit it as part of a measured setup change when refining rear balance, mid-corner traction transitions, or when seeking a firmer rear response without altering suspension geometry.

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