Also check out Wheel Adapters USA. I am looking for the same thing and I found them today. They are made in the USA(called to verify), use a higher grade stud, and are available in multiple depths, 1-3 inches. I'm not saying there is anything wrong with ECCPP but these are a good option and allow you to tune the backspacing a little better.
