If by aero you mean the single-blade affairs then yes, they'll be fine on the rear too. Saying that, I've never found a set that work anywhere near as good as a decent set of normal ones, and the PIAA ones I've been using for the last 5 years seem to be just about the best out there. They may not look as good (subjective, of course) but given that I want my wipers to remove as much water from my windscreen rather than look pretty, I think I'll stick with them
