TAMIYA TA05-IFS/TA05-R Aluminium Motor Stiffener by 3Racing TA05-IF09/LB  [TA05-IF09/LB]

This aluminium motor stiffener is an RC-scale accessory designed for TAMIYA TA05-IFS and TA05-R chassis, supplied by 3Racing as model TA05-IF09/LB. It serves as a reinforcement element around the motor mounting area to reduce local flex under load.

Compatibility is limited to the TA05-IFS and TA05-R layouts named above, intended to replace or supplement the standard motor mount arrangement on those Tamiya chassis. The part is described as aluminium, and its role is to increase rigidity where the motor attaches to the gearbox and chassis.

Installation note: the stiffener mounts at the motor area and interfaces with the chassis/motor mount points present on TA05-IFS and TA05-R. Installation typically follows the existing mounting locations without altering drivetrain geometry, and it is used as part of setting up a stiffer motor support for track-focused tuning.

Tuning role: adding or upgrading to an aluminium motor stiffener can reduce motor movement under acceleration and braking, which helps maintain more consistent pinion-to-spur engagement and can improve repeatability across laps. It is a chassis-level tuning option paired with suspension and gearbox adjustments rather than a standalone performance fix.
