A grand for rotors????
WTF???
If anything they should make the pads softer as they are designed to wear anyway. Sounds like a load of crap to me. Best bet is to rip of a front wheel and check for any uneven wear on both sides of the rotor. Also have a look at how thick they are. Im sure someone here can tell you the minimum specs. If they do need replacing go elsewhere to do it. Subaru will rip you a new asshole.
