Im at 20000 miles, inspection is june. I want to know when ppl usually change their rotors. I dont get on my brakes hard, so im hoping i can get away with only needing brake pads. Any imput on what you guys do would be great so i can start saving for the rotor and stuff if i need them now.

 

You should replace them when they reach the minimum required thickness; that value is listed somewhere, probably the owners manual. Just go and measure the rotor thickness.
