Custom wheels
You might check out Billet Specialties, Weld Wheel, SJM mfg (Bogart wheels) etc. If you have deep pockets I am sure you can get whatever you want as long as what you want is safe to drive on.
For example, some C7 ZO6 and Grandsport wheels are cracking because of the design and the stiff sidewall of the run flats. The wheel on the base C7 Corvette doesn't have the issue. Not sure about the C6 ZR1 wheel. Might want to search the Corvette forums.
