This Factory Pro rear suspension plate is an RC-scale replacement part made for the Tamiya TRF104 chassis. Supplied as Factory Pro O-TCPF04, the plate uses a graphite 2.0 material intended to provide a firmer mounting surface than standard plastic plates, helping to alter chassis stiffness and fine-tune rear suspension response for track use.
The part's role is focused and specific: it replaces the stock rear suspension plate to change how the rear end transfers loads during cornering and acceleration on model tracks. When used as part of a tuning program it interacts with spring rates, shock positions, and roll-center adjustments to influence overall handling.
Installation notes: confirm existing screw lengths and thread engagement before final tightening, reuse factory mounting hardware unless otherwise specified, and check clearance with adjacent components such as rear uprights and shock towers during a dry fit. After installation, perform a short test run and re-check mounting fasteners for consistent torque.
Use this plate when you need a stiffer rear mounting point for incremental tuning on TRF104 race setups, and verify fitment before full track use.
