Hi. The 507 alloys are made by App Tech in Italy , part of the Ronal Group. Iāve spoken to a local CNC guy whoās a car enthusiast and you need a BIG 5 axis milling machine to do a 19 inch rim , not many about that size. Each wheel would need hours of work just getting it set up on the machine , the minute difference from wheel to wheel mean each one needs individually setting up, and no one would want to give any guarantee on a rim. Bottom line is it would be as cheap to buy a new set. So if youāve got black alloys and want to keep them OEM AVOID kerbs and potholes
The route Lee is looking to take with his āOption 1ā looks the most practical way to get an OEM look to the finish.
