for weights, the best thing to use is wheel weights, the stick on ones. I bought a big box full of strips. I used them to balance my kitfox and my rv. what you do is stick them on the spinner on the outside. when you get it right, you drill a hole right through the weight and the spinner, stick the weights on the outer edge of the spinner of course. than you take the weight off and put it to the inside, clean the spinner hole that you drilled, (oh 1/8 hole). than put the pull rivet in the hole and the weight on the inside, pull the rivet and your done.
