Late model cobra 1994-2004 8" x 17" wheels have 5.72" backspacing and will require a 1" spacer in order to clear the upper control arm (nothing to do with brakes).
With that spacer, you are guaranteed tire rub with normal or lowered ride height.

 
Guaranteed tire rub? That doesn't sound good.

I was thinking 7 wide in the front and 8 in the back. Not sure if they will clear the calipers though. It's looking like I will have to roll the fender lips anyway although I really don't want to.

I was hoping not to run spacers but looks to be unavoidable. Bummer. I called/emailed a couple of local places here to see if they narrowed wheels but no luck. There's a couple of sets of bullitt wheels on KSL, the biggest classifieds thing in the area(Craigslist doesn't have the traction in this state for some reason) ranging from 300 ish to 500.00. If I have to do the spacers I might just grab a set of those for the time being. Till I can get some other info on other options.

I would love to post some pics but I keep getting your verification code is invalid or something. Is there a trick to this?

I'm playing around with adapting a 2015 booster and master cylinder over to my 66. It's a 1" master bore master cylinder and its super short. The set up clears the shock tower by a mile. Tons of room. That part is good. I'm wondering if I'm going to run into a bunch of other issues doing this though. Any thoughts? 

but they will clear the brakes and I could have them narrowed if push came to shove? If I can find a place that does that around here

Well, Coys say they aren't making the C67 right now so that's out. The Retro wheels are an option. Any others running the 13.2 brakes with other 17 inch wheel options?

Going to do the 13.2" brakes from a 2013 on my 66. The instructions with the kit says 17's may fit but 18's will for sure. I'm wanting to do the machined coys c-67 wheels in 17". I guess my question is if anyone is running the bigger brakes and 17" wheels? Or are the 18's okay without rolling the fenders?
