I posted this in another forum, wanting to get it over here onto kappaperformance. I went through all this trouble so I can run inexpensive 19x9.5 wheels that are pretty much off-the-shelf. I made a $1,000 gamble on this, it was almost a disaster but I figured it out in the end.
Diameter: 19"
Width: 9.5"
Offset: +45mm
Tire Size: 275/35R19 Ventus V12
Concentric spacer required, hub is 65.1mm
Long story short, these wheels require a modification. You be the judge as to how difficult it is depending on your resources and knowledge. Technically, I was able to get the front wheels fit, but mostly likely because the Big Brake rotor is slightly thicker (also, the hub cap wouldn't snap so I machined them anyway).

Final result:

Front Stick Out:

Rear Stick Out:

Trial Fit:

Machine ~5mm off non-structural part of hub see image, this is the part that hits the wheel:

This shows both the shiney machined surface, and the 2nd downside of the CV axle stick out. I painted the CV axle threads and nut with some flat black paint and blends well:

These wheels on the dyno!
