TAMIYA TA05 rear chassis stiffener TA05-IF13/LB for setup tuning by 3Racing  [TA05-IF13/LB]

Overview of the rear chassis stiffener

This rear aluminium stiffener is a chassis tuning accessory designed to change rear flex on compatible TA05 models. It fits the rear section of TA05-IFS and TA05-R layouts to raise local rigidity, affecting how the rear suspension and tyres pass loads during cornering.

The part is for use on the Tamiya TA05-IFS and TA05-R platforms only, and is CNC machined from aluminium to provide a firm mounting area without altering drivetrain parts. It is a setup item: hobbyists install it to cut rear torsion and fine tune mid-corner rotation and exit grip in combination with suspension and tyre tweaks.

Installation normally uses the chassis rear bulkhead screw points to replace or supplement the stock brace. Confirm screw lengths and check for clearance with your electronics and bodywork before tightening, and run progressive tests on the track to judge the effect step by step.

For precise setup work, this aluminium stiffener is a simple method to change rear behaviour on TA05-IFS and TA05-R cars; combine it with suspension and tyre changes to achieve the desired balance.
