But to your question, right now all I can say is that it will have 12mm hexes front and rear.

Side note, I really hope the new IFMAR rules get enforced. Then all wheels will be standard across all cars. I don't think they've released the 2wd front offset rules yet, but it can't be long. It's kind of amazing to me that the class has been around as long as it has without having stricter wheel dimensions.
