It may be old news, but I found http://www.wheelweights.net/ .

 

Thanks,

This is a great site.

 

Just be sure to stick to that site and not the copies that abound. Christian (the owner of that site) actually updates wheelweights.net, the copies don't seem to get updated. He was a miata guy, that's why the miata forum wheel info is so good.

 

Thanks, I was looking for that site a while ago.
