Before replacing my rear brakes I viewed this board to see what others advise. There was a wide array of advice, and when I visited Groton they had numerous rotors and pads available. My application is that I want my car to stop when I hit the brakes. I ordered regular Brembo rotors (majority of people recommend replacing the rotors with pads), Axxis Semi-Metallic pads, teflon shims and the grease. The job was straightforward and I am very happy with the result. No squeal, the car stops as desired. I can't report on dust yet (600 mi). Rotor replace seemed a bit much, but after reading about problems some have had, $33 a rotor seems like a bargain. I shopped mostly on price. Don 95 T5 150K
