FWIW,

I bought a set of front disks/pads for the Tundra V8 from these guys on Ebay for $104. (Tirerack would have been at least double that). I am 2000 miles in on this set and they performs as well or slightly better than the ATE pads/OEM rotors I had before. These dust a bit more than the ATEs (not that I care) but otherwise things still look fine. The Tundra weighs about 2.5 tons (empty) I believe and, so if anything, these need to handle more load.

Certainly this is no comp for a 4.8iS but maybe at least reference point.
