Description Reviews MINI Wiper Blade - F60 Countryman Rear. These fit both the Cooper and Cooper S for any Gen 3 F60 Countryman. These are a special sized OEM blade that fits into a special arm. It's an easy install for anyone that should only take about 3 minutes. You get one blade that is 9.25” long. Don't think you're going to go down to your local auto parts store and just pick up a set; they are not going to have them. While you're at it, add a front set and do your car all the way around. Wiper blades are recommended to be replaced yearly or soon as needed. The salt/sand of winter weather in the eastern states can do havoc to the blades, as well and the intense sun of the western states. Be ready when you need them the most!
