Right now on my 2002 gs300, i have oem rotors and pads, the rear rotors are ok but the front have a lip and are a little warped. I plan on replacing the rear pads with Akebono proact, and the the front pads with the akebono performance and napa premium rotors. They are nearly half the price of the ultra premium rotors, but all the reviews seem to say its not worth it. I'm also replacing the caster arms on both sides, just because i have them and i want to get it done. Does anyone have any advice or input on the rotors? For the price they don't seem to bad and already come painted. Also any adice on what else should be changed, ball joints and upper control arms have already been changed and I'm at 84k miles.
