TRMotorsport C1M Fitment 15x7 +30?

I love the factory appearance of these wheels, but with a tastier offset - looks really nice. Great choice!
 
Anyone running the 15x7.5 C1's? Seems like it should be a pretty good fit for our cars with the +42 offset.

edit: Just noticed this fittment is a 6ul copy. Should have seen this back when I was shopping wheels for the miata. I had the C1M's on my NB.

And that sizing only rubs on HARD cornerning with 225/45's and 205/50's that run wide, at the height that I'm at (R-Comp Nitto's to be exact).
 
Good to know, though I'm going to start off with a 195/50 summer tire (bfg comp2) so I shouldn't have any rubbing issues. Right now I'm still torn between that and the 15x7 +42's since 99% of the time its just a daily driver. I've still got time to think about it, I'm not pulling the trigger just yet.
 
I see zero reason to go with anything wider than a 195 anyway, all the leading autocross and track guys are running them, and have posted worse times when they've tested 205 and wider. The car's so small and light that 195 is ample grip, and anything more is just pointless mass.
