having done this a few times i can say its either easy or hard depending on the conditions you drive in. the rotor may have seized to the hub if you drive in salt covered roads. if this occurs, you have to spray liquid wrench in there and bang on it with a mallet to free it. also, if there is rust on the hub, you need to resurface the hub. i would suggest buying the pads on rockauto and some raybestos blank rotors from there as well. i think the pp1 and pp2 use the same brakes. should cost 450 total or so. also get the caliper hardware pack from there for 15$. then take it to a goodyear tire shop and have them install it. this would be significantly cheaper than a dealer.
