Tamiya TRF104 Graphite Rear Mounting Plate for Precision Tuning - Factory Pro O-TCPF04  [FP-O-TCPF04]

Track-focused summary

The Factory Pro O-TCPF04 rear plate is an RC replacement part crafted for the Tamiya TRF104 chassis. Built from graphite 2.0, the plate offers a firmer mounting face than stock plastic parts, helping to control chassis flex and sharpen rear suspension reactions on the track.

Functionally the plate swaps in for the original rear suspension plate to change how loads are passed through the rear during corner entries and acceleration. As part of a tuning regimen it complements spring choices, shock mounting and roll-center tweaks to adjust handling traits.

Fitment advice: verify existing screw lengths and thread engagement before final tightening, keep factory mounting screws unless a change is required, and inspect clearances around rear uprights and shock towers during a dry assembly. Complete a short test run then re-check fastener torque.

Fit this plate when you want a firmer rear mounting for incremental setup changes on TRF104 cars, and confirm fit before competition use.
