I believe knowing the maintenance mode on your rear brakes with EPB, and not turning your rear caliper piston when you do the piston push-down are more important than picking up a good set of brake pads. Make sure to read this excellent thread first by tomcat1446:
Rears: Mazda OEM Rotors: Mazda OEM OEM New:
Fronts: Raybesto Element 3 Rotors: Raybeto Specialty - Street Performance; Coated Rotor
Rears: Raybesto Element 3 Rotors: CarQuest Platinum Painted
After driving 100 - 120 miles, I can say that the Element 3's have a better bite and they stop much quicker in wet or dry. Not an apples to apples comparison but considering the front does 70% of the braking with the rear being 30%, I prefer the EHT3's more.
Another thumbs up for the Raybestos Element 3's. I used these on my front brakes and in addition to having better grip and modulation feel, they were a lot cheaper. The OEM Mazda pads and the (separately sold) stainless steel pad guides totaled out to about $100 for online purchase. The Raybestos pads included new guides and cost about $37 delivered. No brainer for when I do the brakes again.
