I replaced my front rotors with Powerslot Cryo slotted rotors, and replaced the pads with EBC Greenstuff pads. It was an absolute bear to replace the rotors- they were rusted on so bad that we hammered on the rotor for an hour, used countless sprays of WD-40, then PB'laster, More hammering on the rotor, only to have it fall off daintily. The second rotor went much smoother after we learned to just PB'laster the thing, then give it Thor-like strikes with a mallet. I mean really whalin' on it.
First rotor and brake pads- 2 hours to do, which may include some time for the run to the autostore for PB'laster.
Second rotor and brake pads- 30 min, TOPS, including reinstall and torque of the wheel, and clean up of the garage.
Bedtime at 1230a, awake for duckhunting at 330a. Brutal, but the brakes are AWESOME. I love doing my mechanic work myself- I know it's done right.
