Perfect-size cooling portal
An easy way to make ROAR-legal-size cooling holes in your sedan’s windshield is to use an old 2-inch-diameter sedan rim. Just place the rim on the windshield and trace around it with a Sharpie marker. Then use a body reamer to punch through the windshield in the middle of the circle. Cut out the cooling hole using a pair of curved Lexan scissors starting at the hole you just created. Be sure to stay inside the traced circle, and your cooling hole will be perfectly legal-sized.
