I'm looking to replace the wipers on my Mk4 Ibiza, and just stumbled upon a product I hadn't heard of before. Bosch "Aerotwin" wipers look quite sleek and a lot less intrusive than conventional wipers. They don't have the usual system of spring-loaded supports that a conventional wiper has; instead the wiper rubber is attached to a single solid strip that matches the curvature of the windscreen. According to the above link, they're now available as retrofit kits. But unless I've misunderstood something, it looks like you have to buy the kit that is specific to your particular car - you can't just buy the correct size like you do with normal wipers. After a bit more Googling, I found this page, which quotes "Seat Ibiza [6K1/6L1] 03.93-", with an item number of "A 533 S" and an order number of "3397118902". But I haven't found anywhere in this country that sells them. Has anyone tried these as retrofits on a Mk4 Ibiza? Where did you buy them, and do you recommend them? Or failing that, does anyone have experience of using them as original equipment on a newer car? Are they any good?
