Nothing wrong with your car. The front wheel on the outside of the track will experience the most wear because it has the most traction, especially if you trail brake a lot to get this 4K lb pig to turn. It should mimic tire wear for the most part. Get used to rotating pads left/right.
It you get tapered wear issues (coning of the pads and rotor) it's because the caper is flexing when hot...not much you can do without cooling or a stiffer system.
