These wheel weights are not "brand" specific. Fitment is assured across many, many brands as almost all these sub-cuts buy and use virtually the same wheels and tires.
They mount with two threaded rods that make a mounting stud. They use two of the square holes in your wheel. They are cast iron. If a dealer sells enough of these weights to his customers, he has them trucked in for his inventory. That's good for the consumer. If you have to order them yourself and have them shipped to your place, I cannot imagine how much the freight would be. Not cheap is my guess.
