TAMIYA TA05 chassis rear aluminium stiffener by 3Racing TA05-IF13/LB  [TA05-IF13/LB]

Rear aluminium stiffener overview

This rear aluminium stiffener is an RC-scale chassis accessory designed to alter rear-end flex on compatible TA05 variants. It installs to the rear section of the TA05-IFS and TA05-R chassis to increase local rigidity, which changes how the rear suspension and tyres transfer loads during cornering.

Compatibility is limited to the Tamiya TA05-IFS and TA05-R platforms as stated in the product name, and the component is machined from aluminium to provide a firm mounting surface without adding drivetrain functions. Its role is tuning-oriented: riders use it to reduce rear torsion and to refine mid-corner rotation and exit traction when adjusting suspension and tyre choices.

Installation typically replaces or supplements the stock rear brace location using existing screw points on the TA05 rear bulkhead area. Users should verify screw lengths and clearances on their chassis before final assembly, and test progressive settings on-track to assess handling changes rather than applying large changes at once.

As a focused tuning part, this aluminium stiffener gives a straightforward way to alter rear chassis behaviour on TA05-IFS and TA05-R cars; consider it as one adjustment among suspension, tyre and weight distribution changes when refining handling.
