The rotor is using all the pad surface area, but I understand what you are saying and already thought about that. Also the rotor is only .5 in diameter bigger then the stock 3kgt rotor. There is another guy running a similar setup on a Toyota with no issues. If these calipers can stop a huge and heavy 3kgt then it should have no problem with the truck. If anything I'll go down to a little smaller rotor later on when I go with a custom Wildwood rotor and hat combo.
