Flow forming aligns the crystal structure of the barrel through heat and pressure. It’s not the same as forging but it gives you much much better material properties on the barrel than a cast wheel. The barrel is the most highly stressed part of the wheel so it helps a lot.
I’ve bent almost every aftermarket cast wheel I’ve owned. I’ve never bent a flowformed wheel. My Apex wheels on my BMW have taken a beating that sometimes I was convinced they would be bent. They’re still perfectly straight and true.
Not necessarily, but I could be wrong. Just because the pockets on the back are CNC cut doesn’t mean the wheels are forged. It could simply be that they make a 4 lug version of that wheel as well. I highly doubt Toyota would offer a forged wheel for this car. You can probably count the number of cars that have OEM forged wheels available on 2 hands.

You go ahead and think what you’d like. I’m an Application Engineer and materials science is part of it. Flow forming does nothing to the hub.
Flow forming =/= forging.
