Keep in mind front tire size and pressure will greatly effect the balance that works best.
I also use different hardness pad compounds front and rear.
Both Wilwood and Hawk have many compounds available that will fit almost anyones caliper.
I typically use Polymatrix B pads on the front and C or E pads on the rear on most cars.
The B pads stop well,but are less agressive on the initial hit ,so they dont lock up as easily.
