My 03 Sedan is going on its 3rd set of front rotors and pads.

Do i upgrade the rotors and pads for the 03 or should i try and get newer 05/06 sedan fronts or a set of Brembo's if i can find any???

Basically is the upgraded 03/04 sedan rotors and pads any better than stock or am i throwing away my $$$.

Any input is appreciated.
