Just by way of an update for those interested:
I contacted all those ideas that were put forward plus seeing if I could convince some Superyacht composite specialists working at Port Pendennis Shipyard in Falmouth UK, to use my original wings as a mould. Unfortunately, every avenue came to a dead-end apart from one! Edeldesign Tuning in Germany had one pair of carbon wings in stock. So, long story short, I'm now feeling very poor whilst they are being packaged for delivery to the UK...... I also now need to work out how to justify this expenditure to the wife....... so has anyone tried sleeping in their Z1, asking for a friend?!

I'm sure those interested would like to know how much and I can't give a final figure yet as I'm still yet to find out how much VAT and duty will be. However, the price quoted to me from Edeldesign was 1,340 Euros for a single wing, not incl. german customs & insured delivery; or 2,730 Euros for the pair with all included. Naturally, I have no idea if this was a standard price (even if they had to make the wings from scratch,) or was a special price as they were in stock. So far, I can report their communication has been exemplary and they're updating on every step of the process.
Although I intend to get these painted, that first picture did make me think (if money was no object), how cool would a total carbon Z1 look...?
