Description Reviews MINI Wiper Blades - F54 Clubman Rear fit both the Cooper and Cooper S. Sold as a set of 2 blades with arms that are 9" long. These are a special OEM rear blade that snaps into a special arm. It's an easy install for anyone that should only take about 3 minutes. 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 set of blades and do your car all the way around. Wiper blades are recommended to be replaced yearly or sooner 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! Note: Sold as a set of two.
