These aluminium rear suspension arms act as a direct replacement for the Tamiya TA07 and TB04 Pro II touring chassis. The machined aluminium construction increases rigidity over common plastic arms, while the black finish offers a restrained, scale-accurate appearance without implying additional surface treatments.
The arms connect rear uprights to the bulkhead, affecting roll centre and toe characteristics at the rear of the car. After fitting, confirm hinge-pin alignment and ball stud location to retain designed geometry. Small changes to toe and camber are often used to rebalance handling when metal arms replace plastic ones.
Follow normal touring-car installation steps: remove the rear uprights, swap in the aluminium arms, and secure pins or set screws. Because aluminium alters the mounting stiffness, recheck shock settings and ride height during early testing to ensure consistent handling.
