Yokomo BD-300MRF Blue Aluminum Rear Suspension Mount (Front side) — Rear suspension mount for MR-4TC BD on-road setups  [BD-300MRF]

Rear suspension mount for MR-4TC BD

This is a blue aluminum rear suspension mount designed for the front-side position of the rear suspension assembly on MR-4TC BD style on-road RC cars. As a separate-type replacement part, it replaces the standard front-side mount to provide a firmer, more consistent mounting surface compared to typical molded parts.

Intended as an RC-scale upgrade, the BD-300MRF helps control swing arm geometry and reduces flex at the mounting point, which can affect rear traction and handling balance. Install it where the front side of the rear suspension attaches to the chassis, checking alignment and fit before regular use.

Use this part when refining on-road setup choices such as roll center position and rear-end feel; it is compatible with MR-4TC BD style rear layouts and is suitable for hobbyists who prefer metal replacement components for repeatable performance.
