I am involved with a company that makes NLA parts for Porsche......
I have been toying with the idea of making a replica of the Halibrands and/or BRM wheels for the GT.
But if you think it would be a good idea maybe I can look into it again.
The whole process takes time though as we need to find an original wheel, digitally map it, increase its size to 18" and 19" mantaining the correct proportions and then run a feasibility study.
Depending on the numbers I think the wheels should end up costing $5,000-6,000 per set, with the hubs another $3-4k (including floating rotors)....
Timewise.... it would take between 6-12 months (plus I would have to finance the run upfront).
What do you guys think?
