These are Gurney-like wheels, probably by Western. Bought the wheels and ran into the usual trouble of not being able to find the right lug nuts. So:
Option #1 you can get 14-12mm conversion lug studs then run the standard washer-ed lug nuts for 12 mm. This is about $40 in ebay parts.
Option #2 I machined holes to press in steel inserts for 14 mm 60 degree taper lug bolts.
Cosmetically either method works, one can maybe argue the 14 mm bolts are better. But there are about a zillion modern cars running around on 12 mm studs.
Also, I welded up curb rash on these rims. If you have access to a tig welder, just use 5000 series rod then file and sand it out. The welding doesn't need to be pretty. Small scuffs can just be sanded and polished.
I cnc machined the center bits. The porsche caps are off of a 928 I believe with the OD turned down, faces polished, and crest stuff sprayed black. Need to redo the cnc work since my original design doesn't clear the front hubs. Oops. Painted the inside of the rims black for contrast.
Anyway, I like the look of these rims on the car.
