Hopefully this will be ok with the mods, if not let me know.

I've been talking a company called Kawasaki Turbos:

They manufacture billet turbo wheels, I saw them in person at the Autosport show and the quality does look to be very good.
Wheels are available for the 16T, 18T and 19T, the original wheel in these are a 6+6 blade design, the billet wheels are an 11 blade, and there is also a billet 6+6 available for the 19T, and there is also an 11 blade wheel with a 6 degree cutback for the 19T.

I do have some of the wheel dimensions available if people want them.

Price delivered would be around £65 each, this is dependant on a minimum total of 10 buyers, if there are more then it may be possible to drop the price a bit, the killer is the shipping cost.
