So, going back to performance breaks issues. I bit the bullet and jumped to get the PowerStop Z23-2035 front and Z23-1594 rear from RockAuto. They should work. I also got the same result on eBay. Using their tool, this is what I found:

However, they are not compatible for a couple of minor details:
Front difference:

They cannot fit at all. I started a return with RockAuto going question after question at their site, and end up telling me that since I did get the right part for my car and because the problem "might" be with the manufacturer, then ist just fair that we split the loss and I have to pay for the shipping back. I didn't have the pictures; I couldn't finish the return. They do not have any humans to ask for customer service. One MUST use their application; by the way, it is excellent, although it takes forever to answer all the possible questions to determine whether they will or will not accept the return. By the time I went to another mechanic and got the pictures, my time to request a return had expired.
Rear difference:

The tiny holes on the rear pads are for a thin clip that, according to the mechanic, helps keep the pads away from the rotor when not in use. I let him install them. He told me that it was so minimal that I can use them anyway. Even when my car now has only the rear pads, I found a difference in braking. I believe these are excellent pads for our GTs if they could fit.
Now I'm stuck with a set of front brake pads. If anyone has a Hyundai Elantra GT, this can be of value. I do have another theory, and maybe if someone takes their pads out for replacement, these may fit on your car. I honestly find it difficult to believe that PowerStop has this problem in ALL their pads for the Forte GT. Another theory is that these pads are meant to be used with their calipers and not the originals.
Sooooo, a WARNING, be aware of these tiny details if anyone wants to install the PowerStop Z23 pads in their GT.
Cheers!
