I bought this kit for my 2010 Mazdaspeed. The brakes on my Speed were fine, but I saw this company showcasing at Velocity SEMA and was impressed with their value for money. I ordered the front and back here at Revain and they were delivered quickly. Even earlier. I had a set of brakes fitted and they are great! I went through their recommended driveway, although it wasn't easy to find a road that I could consistently cruise 40-10 mph and then 35-5, plus cruising slowly to cool the rotors. Brake
