Tamiya TRF104 Graphite 2.5 Rear Brace Upgrade by Factory Pro O-TCPF06  [FP-O-TCPF06]

Overview of the rear upper brace

The Factory Pro FP-O-TCPF06 is an aftermarket rear upper brace built for the Tamiya TRF104 chassis and finished in Graphite 2.5. It is a hop-up component that links to the TRF104 rear upper mount to change chassis flex and rear response when adjusting your setup.

This brace is intended for setup tuning rather than structural repair. Installation focuses on the rear upper brace area of the TRF104, using the vehicle's designated mounting points and standard fastener practices. It provides a single-point adjustment to rear stiffness that complements shocks and anti-roll bar tuning.

Use the brace as one element of a broader tuning strategy: pairing it with different shock valving, spring rates or anti-roll bar choices will illustrate how rear stiffness interacts with overall balance. The information here applies to RC-scale models only.
