TAMIYA TA05 rear aluminium stiffener TA05-IF13/LB for fine tuning by 3Racing  [TA05-IF13/LB]

Rear stiffener for TA05 tuning

This aluminium rear stiffener is a tuning accessory built to alter rear-end flex on compatible TA05 variants. It mounts to the rear section of the TA05-IFS and TA05-R chassis to increase local stiffness, changing how the rear suspension and tyres transfer loads during cornering.

Compatibility is restricted to the Tamiya TA05-IFS and TA05-R platforms as shown in the product title, and the part is machined from aluminium to give a solid mounting surface without adding drivetrain functions. Its purpose is setup-oriented: racers and club drivers use it to reduce rear torsion and refine mid-corner rotation and exit traction while they adjust suspension and tyre choices.

Fitting generally replaces or supplements the stock rear brace using the existing screw points on the TA05 rear bulkhead. Check screw lengths and clearances on your chassis before final assembly, and try incremental changes on-track to evaluate handling rather than making large adjustments at once.

As a focused tuning component, this aluminium stiffener offers a direct way to alter rear chassis behaviour on TA05-IFS and TA05-R cars; treat it as one tuning variable alongside suspension, tyre and weight distribution changes when refining handling.
