Does anyone know the hub to hub width of a 2015 Mustang IRS?
I'm looking for an IRS for a project vehicle and debating between the cobra platform which I know fairly well or the newer 2015+ IRS. The 2015+ IRS is cheaper to acquire.

Were you able to get this info? If not I might be able to get you some measurements Friday. I have a complete rear suspension minus the differential in my garage (diff is getting the case swapped out at a friends).

I have not. Because of this I was leaning towards an 99-04 IRS but if you can post measurements, i would greatly appreciate it as the 15+ IRS is more compact.

I will take a look at it a little later this afternoon and part some pictures with measurements.

Sorry I didn't get those measurements yesterday, had to go help a buddy with some wedding reception stuff. I'll try to get them later today.

Best I can measure from wheel mounting surface to mounting surface is about 67-15/16". Rear subframe bushings are about 37-3/4" center to center. Fronts are about 41-3/8" center to center.

So I've been thinking about the measurements I gave you while I was out of town the past two days, the subframe bushing locations are spot on, however I thinkg the WMS to WMS is off. All of the measurements I've seen for the 2015 track width show 64.9", is there really that much positive wheel offset on the new mustangs?

Just to clarify, I put a straight edge on the outside edge of the center hat of each rotor for the hub to hub measurement and came up with the 67-15/16". I just measured between the rotor hat outer surface to the hub surface through a lug stud hole and the rotor is really close to 7/16" thick for the mounting hat thickness. So true WMS to WMS will be about 7/8" narrower than the 67-15/16" for 67-1/16" by the math, call it 67'' simplicity sake.
