Yeah I was somewhat bummed when I didn't see a rear pad set available in EPad. I'm planning on painting my rear calipers and putting on new rotors so I'm determining what rear pads I should go with. It seems that the 48i, 50i and older 35d rear rotors and calipers have an ePad application so I was thinking of converting but it's probably more work than worth it, especially when I already have new rotors for the rear.
