Tamiya 54740 TA07 Medium Suspension Arm D-Parts OP-1740 - Tuners Edition  [54740]

Trim understeer with medium flex suspension arms

Racers aiming to refine TA07 or TRF418/419 chassis behaviour will find the Tamiya 54740 TA07 D-Parts (Suspension Arm / Medium Type) a useful option. These medium flex arms help reduce abrupt reactions on low grip surfaces, improving predictability through corner phases.

Materials and compatible models

The medium material is positioned between the softer fiberglass reinforced plastic on standard TA07 parts and the harder carbon reinforced plastic seen on TRF418/419 items. That blend provides sensible flex with adequate strength across different track conditions. The pack contains one front arm and one rear arm and is compatible with TRF418-design suspension and TRF419 D Parts (Item 54691).

Practical fitment notes

Bear in mind each package contains only a single front and a single rear arm, so two packages are necessary to fully equip a car. After fitting, check suspension movement and run some low-traction test laps to confirm handling changes before committing to further setup alterations.
