It pairs with Tamiya's FRP Plate for Super X Chassis (No.242), which reinforces the front bumper and roller area on the same chassis family; fitted together the two stiffen both ends of the car. Its compatibility list runs slightly wider than that front plate's, additionally covering FM-A, AR and MA chassis cars, since a rear stay has less to clear than a bumper reinforcement does at the front. As with the front plate, it only positions rollers correctly if mounted rigidly — any flex under cornering load defeats the purpose of adding it.
