last summer i replaced my brakes, pads and rotors, front and rear, with the R1 Concepts drilled and slotted rotors, and their corresponding pads. I am much happier with them then i was with the OEM brakes. the OEM brakes heated up and caused too much noise for me. Also i get very little dust from them. they are a little more than OEM but not much. definitly a good option.
