Serious TA07 builders will appreciate the Tamiya 54789 carbon fiber rear stiffeners as a tidy reinforcement option. These 3mm carbon fiber pieces replace the OEM plastic parts to add torsional stiffness where it counts. The upgrade performs best on sticky tracks where chassis rigidity plays a major role in lap consistency.
By limiting lateral movement, the carbon stiffeners create a more predictable platform for suspension tuning. The firmer connection between chassis and bulkheads improves feedback and response during aggressive driving, helping drivers extract more consistent pace from their setups.
