Manufactured as a direct replacement, these aluminium rear suspension arms suit the Tamiya TA07 and TB04 Pro II touring car platforms. The machined construction increases stiffness over typical plastic arms while the black appearance gives a clean, scale look without implying extra surface treatment.
The arms form the mechanical link from the rear uprights to the bulkhead, playing a role in roll centre and toe settings at the rear. After swapping components, verify hinge-pin alignment and ball stud positions to maintain the intended geometry. Small setup changes to toe or camber can help fine tune balance after fitting.
Fitment uses standard touring car procedures: remove rear uprights, replace the old arms with these aluminium units, then ensure pins or set screws are correctly secured. As aluminium alters stiffness characteristics, retest damping and spring preload during your first run to confirm predictable handling.
