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

Rear stiffener overview

This graphite rear stiffener is an RC-scale replacement part designed to alter rear chassis rigidity on compatible Tamiya TA05 family models. The part provides a direct way to change how the rear of the chassis reacts under cornering load without modifying suspension geometry.

Compatibility: fits Tamiya TA05, TA-05IFS and TA05-R models as identified in the product title. Use this part when you want a straightforward chassis stiffness change that works with the stock rear mounting points and hardware on those TA05 variants.

Installation is straightforward: the stiffener mounts to the rear chassis area using the vehicle’s existing attachment points. It is supplied as a single graphite plate intended to replace or augment the stock plastic brace, so expect a noticeable shift in torsional stiffness at the rear once fitted. No additional components are required beyond the chassis’ existing fasteners.

Tuning role: increasing rear chassis stiffness tends to reduce rear flex, which can make the car turn in more crisply on high-grip surfaces and during aggressive transitions, while excessive stiffness may reduce rear compliance on rough tracks. Use this stiffener as part of incremental setup changes alongside suspension, tyre choice, and roll center adjustments to achieve the desired balance.
