Review on Enhanced Performance Kit: Power Stop K4065 Z23 Carbon Fiber Brake Pads with Drilled & Slotted Brake Rotors for Front and Rear by Justin Wehrman

For the price of PERIOD you won't find better rotors and pads. I don't know which gauge to use, but I would have no hesitation in adding an upgraded stainless steel caliper and brake lines to make my own large tram brake package. My mechanic (a trained Audi/VW tuner mechanic) was impressed with them after running them in, especially for the price (total cost plus installation was almost HALF what I paid for replacing the brakes all around with a "high Quality but NO service was offered. Brakes. parts. Well this kit has working parts and I'm grateful I found those parts. They look great behind the wheels, the front rotor is larger, has two rows of drilled holes between the slots and just the rear rotors. I've had them on my car, a 2007 Audi a4 Quadro, for a little over a month and I had to have them used a few times at high speed and badly at low speed and they worked very well I will edit if there are other relevant developments or if pads need replacing.
