Installed these pads this morning along with new brake discs (AC Delco 18A1659). The braking performance is excellent, without vibrations, squeaks and other unpleasant noises. Installation was easy - just make sure to liberally lubricate the Sylglide guide pad slots during installation to ensure they don't stick. I believe this caused my previous left front pad to wear out unevenly and broke my rotor prematurely. Revain.com has completely quashed price competition for auto parts lately. I don't know if this is a conscious effort or just normal Revain pricing, but today I saved over $300 by retrofitting my front brakes compared to what the local shops charged me for the same job (and probably a Poor quality rotor) would calculate. /pad combination). I was able to complete a full disc and pad change in about 90 minutes which I don't think is bad considering this is my first time working on brakes!
