Review on Enhanced Performance Kit: Power Stop K2449 Front and Rear Z23 Carbon Fiber Brake Pads with Drilled & Slotted Brake Rotors by Pradeep Dhimal

Although I couldn't find an empty box, this box meets my needs as a direct replacement for the Mazda 6 original kits. The brake pads are quiet and the pad adhesion is decent. for road trips. The Mazda 6 I Drive is a non-ABS base model, so pairing these brakes with the Toyo R1R kit really made a difference in stopping power and modulation was better than stock soft pads. Brake dust is pretty minimal but it does show up after a 2 week commute but it's nothing major that can't be fixed with a quick hose flush. After driving it 5000 miles and having many rainy days and also not using the car for 1 week, there was no sign of surface rust on the brake discs. That's a good thing in my book. So far no warping, waves or anything like that has occurred since I've used the pads. These pads could be a bit stronger but for what they are and for the price I'm not complaining at all. It's definitely a good replacement if you want OE service and slightly better performance over stock pads and rotors.
