Don't know yet. Some are saying the pieces are required, some are saying OEM is ok if you don't run the required pieces. Will have to see how it shakes out the next few weeks as details come in.


Stage 2:
Tires: size 225/45R17, minimum tread wear depth. The spec tire brand will be named later this year
Wheels: 17x8, minimum 17 pounds, minimum wheel offset 40

And wheels/tires are "Stage 2". Don't even know how that will work yet.
