If the pads don't fit and the rotors are correct, then the pads must be wrong. You can check this by buying a set f et on th he local parts store. If they don't fit you can return them. If they do fit...you know the pads you hot are wrong.

If the cheap parts store ones don't fit either, then the rotors are the culprit.

GT and cobra stuff completely different up front. If you have cobra calipers you need cobra pads.

If you're using aftermarket lines with stock banjo bolts, the bolts are too long, and may be preventing the pistons from retracting all the way.

I had this happen with a customer. His bolts going through the brake line were too long causing the pads not to fit. Caliper piston wouldn't go back all the way. Ground the bolts down and no problem.

The thickness issue is usually with rear pads. Gt rotors are solid and cobra rotors are vented in th he rear. The actual calipers are the same ( bracket is different ). Cobras take thinner rear pads shaped exactly like the gt.
