Description Reviews MINI Rear Wiper Blades come in three sizes to fit both the Cooper and Cooper S for any year or model. These are a special sized OEM blade refill that fits into the special rear arm. It's easy to figure out what you have, you just have to look at the arm for Gen 1 cars; Gen 2 cars are all the same. The Gen 1 cars had two different blades, what we call the “plastic blade” or the “metal blade." By looking at the above photos you can quickly match up which blade you have. Just make sure you put the correct one in. If you have any questions, give us a call. 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 refills to the front and do your car all the way around. Find Countryman blades here. 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! Note: Will not fit Clubmans, find the special rear blade here.
