I recently purchased the Chromebrakes drilled and slotted rotors and couldn't be happier after install. Out of the box, they certainly look the part. I paired these up with the Chromebrakes Ceramic pads and the grip is unreal compared to stock. I wish I was able to quantify it better, but there is a noticeable difference in stopping distance. They operate quietly, so I'm not sure the disclaimers of potential wind noise is necessary. Overall, fantastic quality, great stopping power, and worth the extra money.
