PERSONALLY, I like Hawk HPS pads, I have them on the front. They DO NOT FADE in a panic stop from 80mph (don't ask how I know this...) and their dust is about 1/4 of OEM's.
My car stops a LOT better now!
I got mine online, I THINK from TireRack - but I know I googled them and went to where the price was lowest.
Pretty sure it was TireRack.
