Small Maintenance Tip
Here's a small bit of info that may make your life a little better. I wanted to get the winter wiper blades off the GTO but didn't want to just pop the 1 yr old factory blades back on.
I also noticed that the factory drivers side wiper assembly has a wind fairing on it to create downforce and keep the blade in contact with the glass. I didn't want to give that up either.
I found that Bosch makes a blade they have branded ICON. It has a wind fairing built into to the entire length of the blade. Expensive ($23 bucks apiece), but I bought a pair. The first thing you notice when you take them out of the package is that they are limp!!! They seem to have no embedded metal for rigidity. Should hug the window really well.
Sure enough, when the blades hit the window, they clamped to the glass like a wet chamois. Even at the outer edge of the passenger side where the glass curves sharply they were in contact with the glass.
I can only imagine that at speeds of 35-65 mph the air pressure would increase the contact. Anyway, I had a chance to test them in the rain once so far at speeds from 25-85 mph. Excellent!!! You get the full 22 inches of cleaning from the blade.
