I am already on Revision #2. First mpg significantly improved on regular relax driving. On the the aggressive side , you will feel linear power on all RPM range. 60+ is a breeze. So when you are in the interstate you just keep on smiling.

You can call Sp Performance and they can make you the rotors you prefer. I ordered the Diamond Slotted Rotors. You won't see it at their website but you can call and order it.
