I've driven them about 6000 miles and they work very well. Installation on my 2006 WRX was easy - they matched perfectly. Significant improvement in braking performance compared to standard pads. I am currently using them with Centric "Black Hat" non-slotted rotors and am very satisfied. And they're no louder than stick. The only downside is the dust - prepare to clean the wheels frequently. I would buy them again.
