11" wheel rotatable combo

We have a thread over on BossMustangsonline about fitting 11" wheels and larger 305, 315 tires at each corner. Wanting a set-up you can rotate keeps the Enkei 10.5" +38 the only choice for a larger wheel track combo while staying with a stock offset type strut. After thinking about it for a while I wrote the following:

Neema's idea of a +50 ET 11" wheel to use in conjunction with the Cortex offset struts gave me my latest idea. An ET44 11" wheel has about a 7.7" backspace. This will stick the 11" rear wheel out another .4" as compared to the ET55 wheel. That seems to be around the same amount of poke that the Enkei +38 ET wheels have, but with the extra inboard 1/2" of wheel width. In the front a 15mm H&R hubcentric wheel spacer could be used, like the one Blowfish Racing sells, to give an effective wheel backspace of 7.1" which should clear the strut. If my math is right that would be a feasible 11" rotatable wheel combo with a track usable front spacer and acceptable amount of rear poke. I think the rear tire should tuck in even better because its pulled inward a bit from the extra wheel width. Thoughts, opinions?

The only experience with wheel spacers has been the smaller stuff, about 1/4" just to keep a tire from rubbing, so if anyone has any feedback on using a larger spacer, either from the safety or durability standpoint I'd like the input.

I was thinking about doing something similar. My rears are 20x11+51, and was going to stack washers on the lugs until the wheel had an acceptable gap from the strut, measure the washers, and order an appropriate spacer.

A 18x11 ET56 would need about an inch worth of spacer to be used on the front with a conventional front strut setup FWIW. NO idea on the offset front struts but obviously less...

The offset struts seem to give around an extra 1/2" of backspace. By decreasing the offset of the wheels from ET55 to ET44 I can use a smaller 15mm spacer that's hubcentric and slips over a set of longer studs thus equaling the 1" of offset difference required with only a little bit of tire poke in back. I assume with a hubcentric spacer the wheel hub area is extended for wheel mounting purposes and to take some of the load off of the studs. Getting a set of the Enkei wheels is far simpler and cheaper, but it might be worth the extra complication and expense of an 11" wheel if the 15 mm spacer is viable and safe.
