315 mm = 12.4" I haven't measured the actual width. Yeah, I'm really happy with the look!

 

How much backspacing do you have with those wheels? Could you possibly snap a shot to show how much the tires stick out past the fenders?

 

4.5" backspacing. I'll get a pic in the morning.

 

Looks great. Love black wheels!

 

Here are closeups of the tire and fender. I put a level on the tire and measured just over 3" back to the fender. This is with 4.5" backspacing. I had rub on the air dam at full turn and trimmed it a bit.

Thanks for posting. I'm doing a similar setup on my mango tango and have been debating on all black wheels or polished with a black rim. I like the all black!

 

Oh sweet! Those don't stick out too far. I think the german polezei will let that slide when i get mine setup. Again, your rig looks great
