Question: When you drilled your hubs for the ARP wheel studs did you also have to drill out the rears?
I also really like the CF5. I ran that face-style on my Mustang for the past 3 years and absolutely loved them. Classic 5-spoke look, simple yet elegant, easy to clean... On the other hand I also like the look of the F14s, but it pretty much came down to available sizes that made that decision for me. SDC profile and 12" to 13" widths available in the F14, previously with as low as +6 offset, but now with UDC profile they go as low as -50 offset which is nice. I would not hesitate to use a spacer with CF5s or SDC-profile F14s if needed.

As for the hubs, remember the rear hubs (if you go with IRS) are already M14x1.5 studs as they are S550 Mustang spec. FFR would have you replace the beefy M14 rear studs to match their 1/2" studs in the SN95 front hubs... but I prefer to keep the larger of the two. Especially since it's standard issue on many (most) performance cars today. Better clamp load, higher yield strength, handles frequent torque cycles better, etc. To achieve this, you only need to ream out the front SN95 hubs to roughly the size of the rear hubs holes. There's science behind knurl diameter, material displacement, and so on. But long story short, I have done the science and have confirmed results. Buy a 0.612" diameter reamer from McMaster Carr, and within 5 minutes at the drill press you're ready to press in a 0.625" knurl-diameter M14-stud of any length you desire. The reamer is $50, and has little other use besides this, but very much worth it to do it right. Cuts the hub material like butter. Do NOT take a regular twist drill to your hubs!
