That is not the end of the world, but I'd do all 4 corners--especially if you start seeing very high temps on the front rotors.
Very true. I ran Ferodo DS3000's (Track Pad) in the front and the DS2500's (Aggressive Street Pad) and observed front rotor temps around 920deg and rear rotor temps around 580deg. Needless to say, I immediately purchased a set of Hawk HT-10's and now get around 650deg front and rear consistently.
