I have 72K on my car and think its about time to replace the rotors / pads on my brakes. I have replaced the pads before, but I am thinking about buying a new setup for my car. I do not want to spend a ton, but I am thinking about power slot rotors for the front and back and getting hawk brake pads. Should I look into converting the fronts into the Mach 1 / Bullit setup? Are power slot rotors good to have? Do they warp like regular rotors so are you SOL when that happens and have to buy new rotors instead of turning the normal ones?
