I once ordered them on the off-chance because they were on sale and the AR502S was available twice in the range. You don't need to call them "FBW", all Aerotwin have the same wiper blades. It would be much more important to state that it is the "RETROFIT" model. That is, the one you need for older vehicles, where the wiper arm only makes a "hook" at the end. (So actually the simple system that vehicle manufacturers left behind for something complicated, proprietary). So these wipers fit extremely many older vehicle models.
