Not trying to bad mouth your products. I made the mistake of buying drilled and slotted rotors with out doing research. Drilled and slotted rotors for everyday driving is an overkill. More looks then function with less braking surface.
My issue with these rotors is that after about 10-15k miles, the brakes don't feel sharp anymore. They give that warped/no bite feeling when pressing the brakes. In my head drilled/slotted means the brakes stay cooler and way less prone to warp. After the above miles occurs these rotors don't hold up as they are supposed to as stated in online descriptions.
Another issue with these rotors is that they gave me wheel shake from day one. How do i know the answer to this. Bought new rotors and pads, went for a drive and the shake is gone. Again im not saying your products are bad. Maybe i just got a bad set or something. Who knows. To each is their own with their brake experiences. This is just my trip.
