Make sure you get the correct size rotors.. I got burned twice earlier this year attempting to replace brakes on an 02 Arc. Mine had vented rears (different from the other models), and larger front rotors. I'd measure your existing setup to make sure you get the right rotors. PLUS, the info suggests there was little rhyme or reason to which size setup the Arc models got.
I got smaller fronts, and non-vented rears.. Had to re-order twice to get the rights parts
