I noticed that rules problem too. One of the ITR cars I considered has pistons that are coated from the factory. Now, of course you can buy OEM pistons and they will be coated too, so you don't have to apply coatings. And naturally the stock motor has pistons that are coated. But the rules say no coatings period.

Illegal car right out of the box.
