Tamiya TA05 Tuning Rear Stiffener Graphite Plate TA05-05/SG by 3Racing  [TA05-05/SG]

Technical overview of the rear stiffener

This single graphite rear stiffener is designed as a replacement tuning part to alter rear chassis rigidity on Tamiya TA05 family models. It provides a direct adjustment to rear torsional response without changing suspension geometry pickups.

Compatibility note: compatible with Tamiya TA05, TA-05IFS and TA05-R chassis variants referenced in the title. The plate is suitable when a precise increase in rear stiffness is required while retaining factory rear mounting points.

Installation procedure: mount the stiffener to the rear chassis using the car's existing attachment points and fasteners. The component is supplied as one graphite plate intended to replace or reinforce the OEM plastic brace and will produce a measurable change in rear torsional stiffness when installed. No additional parts are generally necessary.

Setup and tuning: increasing rear chassis stiffness tends to reduce rear flex, yielding crisper turn-in and more stable transitions on high-traction surfaces; excessive stiffening can limit rear compliance on rough layouts. Use this plate as part of incremental setup changes, recording handling changes after each adjustment alongside suspension and tyre modifications.
