I received the same message today immediately after having a VIN assigned. I don't want the CORE wheels either, instead want the Cyber Wheels and AT tires that I originally ordered.
Responded to the text message accordingly, but haven't heard back yet.
What ended up happening with your order...
Enjoyed reading this, thank you for sharing. My current vehicle / daily driver is this exact Raptor (but in a different color), and I have a Cyberbeast on order. Just like Dan, I love my Raptor far too much to replace it, so I'm keeping both.
