The upgrade I did on my Ford was an actual upgrade, not a change in rotor manufacture or pad compound.
I put on larger calipers (SSBC) on all four axles plus I had a shop take off the existing brake lines and remake the brake lines using the existing hardware but replace the hoses with SS braided hose. The calipers are much larger - I think the swept area is about 35% larger. Also, the fronts are 6 piston and the rears are 3 piston so the the piston force is evenly distributed.
The pedal feel is just as good as any of my race cars, which really makes it fun to drive even though I only drive it once or twice a month.

I haven't yet experimented on changing the pad compound because the ones provided by SSBC work fine.
