The Tamiya 53905 - TA05 Aluminum Chassis Stiffener provides targeted reinforcement to the TA05 chassis, reducing unwanted twist and giving a firmer platform for tuning. It is suited to drivers seeking smoother steering inputs and steadier high-speed behaviour.
Aluminum is chosen for its good strength-to-weight properties, reinforcing key areas while keeping the car light enough for competitive performance. The result is improved consistency lap after lap.
The design aligns with TA05 mounting points so you can fit it quickly and return to setup work. It is a useful component when experimenting with roll centre and sway adjustments for track-specific performance.
