With CT Springs, what is the lowest offset and largest width on an aftermarket wheel that will definetely not rub?

I have done searches, but get conflicting answers to this. Any experts out there in wheel offset. In purchasing aftermarket wheels, what specs should I definetely get for the money?

Help is appreciated!

 

8" width with a +50 offset

 

Okay......it's down to 3 wheels on a silver CLS.

1. Konig Prophet Opal
2. Giovanni Genoa Silver
3. G Racing Kuma Hyper Silver/Hyper Black

Anyone like any of these? I have pictures. If someone can help me load them, I will send the to you. Thanks.

 

I had the Prophets in Chrome, 18"x7.5 w/ offset of 45. I had no rubbing at all!
