yea, toyota wont make its own wheel.......thats not what they are in the business of doing. They use 3 or 4 different wheel manufacturers that are slipping my mind right now...to develop/produce their wheels. Its all for cost-savings. I know that toyota will submit a design that want emulated......and BBS or Enkei or another manufacturer will develop CAD drawings to surface and big safety issues (structuraly) with the design . - T
