The 3Racing TA05-05/SG Graphite Rear Stiffener is engineered to strengthen the rear torsional stiffness of the Tamiya TA05 chassis. Its graphite construction reduces chassis compliance at the rear bulkhead, improving repeatability of handling through a variety of cornering loads.
Increasing rear stiffness alters load transfer characteristics, which can make steering response more linear and allow finer tuning of damper and anti roll bar settings. Use incremental changes and log setup differences when evaluating lap time impacts.
Install with standard hand tools and verify secure seating at the mounting points. After initial runs, re-torque fasteners and inspect for even load distribution. This helps maintain consistent performance and prevents progressive loosening under race loads.
