Does anyone but SSBC have 4x4.5 disc brake kits with rotors that are 4x4.5. Did any other application ever even use these or are they unique on the I6 mustang?

drill your own, it can be done if you start by making a jig. I have redrilled rotors and hubs for several applications including my Jaguar IRS project. Here is an excerpt from my Jaguar IRS page and the technique I used should work for you.

"When I first suggested to some other car enthusiasts that I was planning to drill the pattern myself, I was told not to drill the pattern because it would be almost impossible to have all 5 holes be in the correct spot. I pondered the issue and, at first, thought about making a 10-hole jig. (5 holes each pattern) Problem is, I still would have a hard time getting all 10 holes in the correct position. One day while contemplating this issue, I had an epiphany, instead of making a 10-hole jig, make a 3-hole jig and rotate it from position to position. I made the jig (Homemade Tool # 4) by drawing 2 circles, a 4.75ā€¯ circle with a 4.5ā€¯ circle inside it. I then measured the distance between two studs on the Jaguar wheel flange and plotted those 2 points on the outer circle. Using these two plotted points I measured between them and plotted a center point on the inner circle. The drawing was then transferred to a piece of steel and the three holes were drilled out, .5ā€¯ inches on the outer ones and .125ā€¯ for the center hole. The jig can now be bolted to the flange and a pilot hole drilled. The beauty of this jig is that even if the pilot hole is not perfectly centered, as long it is on the 4.5ā€¯ circle, it will be in the same location between the two studs on all 5 holes, giving a perfect star pattern. After creating the jig, I purchased a cheap Chevy rotor and drilled out the Ford pattern to ensure that the jig was accurate prior to drilling the hub."
