Funny, i just did the fronts this past weekend...
Dealer costs:
Front rotors, $250 each
Front pads, $240
Wear sensor, $59

Napa auto
Front rotors $120 each
Front pads, $130
wear sensor, $29

Take your pick....i went with the Napa, dealer was closed on saturday here, closest one is about a 45-1 hour drive one way.....when gas here is $1.48 a litre(3.78 litres to one gallon) wasn't really worth it to me....atleast for now....
So far everything feels just the same....it stops, decent....its a grocery car, not a high speed racer machine for me....
