Wheel/tire selection check for '66 vert

So now comes the time to start shopping for wheels/tires for my '66 convertible... One would think that after 50+ years of experience with the Mustangs, this should be a straightforward process with all of the kinks having been worked out. Reading through this forum and a multitude of vendor's websites this hardly seems to be the case as contradictory information abounds! Having dialed in to what I think I want to do, I wanted to toss this out there just to see if anyone else sees any issues that I may not be accounting for...

Currently, I am running slightly-larger-than-stock size tires (205/75R14s) on the OEM 14" wheels. Current fit and function (no rubbing in wells during turning nor bottoming out) are fine with my current suspension mods which include Shelby/Arning drop & Scott Drake progressive rate springs p/n C5ZZ-5310-PR in front and 4.5 mid-eye leaf springs in rear (see photo).

My plan is to go to 15x7 wheels at all four corners (either Styled Steel w/ 4.625" bksp which I'm leaning towards or possibly Magnum 500s w/ 4.25" bksp); to these would be mounted tires with a slight size (width) offset... 215/65R-15s in the front & 235/60R-15s in the rear.

My car came factory-optioned with front disc brakes and, while I do plan to upgrade the components (rotors & calipers), I will stick with the OE size so this is unlikely to result in fitment issues down the road; likewise with the rear drums which I'll likely bump up to the (Shelby) optional 10x2.5" with no plans for conversion to discs in the back.

Am I missing anything? Anyone see any problems?

You should read the thread parked right next to yours in the forum:

"Help! 66 tire and wheel fail!"

It sounds like your 4.25" backspacing will work, but there are a couple of comments about anything larger than that needing work on the upper control arm shroud for clearance. So the styled steel wheels you're looking at might be a problem.

I'm no expert, just making a comment because I read the above thread before I read yours!!

Brad:
I did previously read through the thread mentioned and the issues brought up therein were the cause for my my initial concern. I'm not sold on the 'Styled' type, and the backspacing issue gives me reason for pause. I'm just hopeful that someone can chime in who is actually running (or has tried) a similar setup and who can definitively point me in one direction or the other. ~pws~

I have the following wheel tire combination on my 66 Coupe and although I don't have any clearance issues when turning, I do have clearance issues when i hit a ip int the road on both the front and the rear. They are just a little too wide to fit inside the fenders.

Rims: Vision Torque 143 15" rims.
Front215/60R15
Rear235/60R15

Looking at the specs for the 143 Torque at the Vision Wheel website, I noticed that they don't provide a spec for backspacing. Any idea what this is on their 15x7 wheel?
