I own a 2006 Acura RL with A-Spec performance package. I have always used OEM disk pads and rotors. Recently I decided to give the Power Stop brake kit a try. The performance has been crazy fantastic. After 15 minutes of rotor / pad conditioning, i decided to do a hard brake from 70 mph. Good thing I was wearing my seatbelt or I'd have gone through the windshield. Performance exceeds my expectations!
