Tire size
If you go to Tire Rack and find the actual tire that you looking at and then go to the specs tab. You will see a listing of all the info for every size offered for that tire.
This page shows more than an inch difference in Diameter. This may throw your speedometer off by quite a bit without recalibrating it.

2006 Mustang GT shows two (factory) size options: 235/55/17 & 235/50/18. What about 235/60/17?
Let’s input those numbers on RimsNTires
1. 235/55/17 = 27.2” (690mm)
2. 235/60/17 = 28.1” (714mm)
Suspension/ Fender clearance shows the same. Will fill out the wheelwell by extra 12 mm. Acceptable for most cars. When speedometer reads 60mph (96.6km/h) actual speed will be 62.1mph (100km/h): 3.5% faster.
So they are little taller, fills gap 12mm more, and reads a little faster. If the car is not lowered, then it seems to be ok.
I would stay factory sized... unless you already bought the tires. Otherwise consider 18-19” rims for shorter (40-50) sidewall. 60 & up feels like a truck tire to me.

I have read that Ford still sizes the wheels and fender openings to accommodate tire chains on the original size tires. So that means you have at least 1/2" extra space on the radius or 1" on the diameter. So I think the taller tires would be OK but can't guarantee it.
Personally I am not crazy about the super low profile tires either, for street use around here, because there are too many potholes and other things that could damage the wheel; but I am talking 30 or 35 aspect ratio on 19" or 20" wheels. 60 aspect ratio is pretty tall and squishy for my preferences but it's your car so it's your preference.

I changed to BF Goodrich G-Force Sport Comp 2's in the factory size. They're also a little taller, and alter the speedometer reading a little.
But they are the best tire decision I made for the Mustang. They stick to the road like glue, corner well, and are secure feeling in the wet. Ride is quieter too. I will be getting them again.
No rubbing at all, by the way.

Except you failed to mention the Comp TA's were discontinued quite some time ago and replaced by the G-Force Sport Comp 2 tires. Therefore where and how are you going to be able to get them again lol? However, if the Sport Comp 2's are similar and provide a slightly taller sidewall as the Comp TA's? then perhaps the Sport Comp 2's would be a possible option for the OP to consider
