Just noticed this winning reply

"The 80 hole drill process on the assembly flange is used often times for weight reduction / valve stem hole alignment should the rotation of the center disc be slightly off from the
pre-drilled hole on the lip."

So does threading these extra holes also help in weight reduction LOL. It was clearly a mess up and you would think that at the price they where sold they would scrap that one wheel and make them right. Just shows the greed for money!
