The front pads wear a lot faster because when you decelerate, the weight distribution of the car shifts heavily to the front.
I also use Textar pads and am qute happy with them. I avoid "lifetime" pads: the Mercedes or OEM pads have a much shorter life and produce more dust, but the "lifetime" pads just don't stop the car as smoothly, quietly, or effectively. Which is more important?
