by GREAT research EBC (made by the British) is an excellent pad. as far as performance is concerned. They are also of great value. They sit in my Audi A4 and my wife also has a Sub Impreza kit. Brake dust is slightly but not completely eliminated. When you combine these high-end pads with perforated/slotted rotors and Stainles adjusting brake lines. You have better stopping power. far above the OE level. Standalone, these launch pads are AWESOME on their own. I would highly recommend them to anyone who is SMART, sane and looking for the best level of performance at the best price. Green stuff is your answer.
