Door seal rubber blocks
Hi Lappy, Ricardo is 'da man' that made the rubber blocks to reduce that annoying wind noise when the window is up on our early X's. Ricardo sent me two blocks when he was in the post-developmental stage with them, and I can assure you they do work!
You gotta take care fitting them, making sure you don't cut too much of the original rubber door weatherstrip away. Use a 'permanent' fix type adhesive to secure the blocks into the weatherstrip, and you are done!
