Well, after looking at a ruler and the pads again I think they must be an 1/8" to 3/16". I manage to convince my girlfriends that 5" is actually 12". I guess my tendency for gross exaggeration has gotten the better of me. Anyway, based on most replies, I'm glad to know what I am hearing is the norm and not the exception. Thanks to all.
It's possible someone put EBC "HH" pads in the front. A lot of us use them because they work really good. They are noisier than stock pads but they are like having power brakes
