Machining the wheel from a solid piece of material is more expensive, but allows the manufacturer to more easily change wheel designs as the market moves and the technology develops. Often, rather than choosing an off-the-shelf cast wheel from one of the major manufacturers like Mitsubishi or Garrett, they can customize the wheel to their unique hybrid turbo.

The videos of the 5 axis CNC's making these wheels is really neat to watch.

thanks. I always hear about "billet wheels", then I ask what the advantages are, and people shrug. I figured the profiles were different, because that's a lot of work to make a standard wheel.

loving the detail put into this build btw. can't wait to see the finished product!
