Jumping the gun a little here since they aren't "technically" on the Mach yet (or even delivered)...buuuuuut:
I've was flirting with pulling the trigger on some CCW wheels for awhile now & a few weeks ago I sent an email to them to sort of just 'feel them out' & next thing I knew - I purchased a set of CCW wheels. haha
$3,800 later & I'm the owner of four brand new 3-piece CCW Classic forged wheels.
After talking to them about my specific setup - They recommended I go with 18x9's (w/ 6" backspacing) for the front & 18x11's (w/ 7.25" backspacing) for the rear.
I went with a satin black powdercoated center w/ a gloss black powdercoated shell. I'm having both the 'lip' portion as well as the barrel behind the face powdercoated that same gloss black (usually left 'raw'). I also opted for the polished ARP hardware (12-pt stainless) & for the centercaps - I went with the satin black setup with the CCW logo machined out and left aluminum.
I'm not exactly breaking any news on this next part - but I must say, the guys at CCW have great customer service & know mustangs very well. He asked very specific questions about my brake setup as well as other suspension & tire modifications. Top notch service for sure.
Here are some random internet pictures of what my setup will sort of look like:
