Agree with you 100%just a word of warning on "economy brake pads", and this is my own experience. I once got lazy and put in some pads from Kragen to the rear calipers before an HPDE event. It took just a few laps and as I came down the hill and braked for chicane, i felt the brake pedal gave in a bit, a puff of black smoke came out and behind. I pulled off the track safely to see what happened. Turned out the new rear brakes pads were completely disintegrated and nothing but back plate remained. Luckily my rotors were new and the pads didn't fall out or i'd had lost all brake into chicane! ( and a fence not too far after )
Lesson learned, "economy" parts may not be economy solution. They may work, but may not be dependable.
The Ghibli has a lot horses and weight, please give it some good pads. Stay safe.
Car is heavy + OEM pads is a good idea.
