This is the first car that I've owned that's ever cropped up this problem. I'm getting front end vibration on my stock 03 from higher speeds. I have gone through my factory pads and the dealer resurfaced the rotors and put in new Brembo pads. Not too long after that, some vibration started cropping up. I was hoping that it would get better as the brakes wore, but it seems to be have gotten worse.

I'm guessing that one or both rotors are warped, the problem gets worse as the brakes get hotter; though sometimes it seems to be barely there. Sometimes the problem can be pretty severe when things get hotter.

Can the rotors be rescued by grinding them again, or am I looking at new rotors?

 

do a search there is a great thread about this and brake pad transfer

 

I'll look at it. I recently did the rear's myself w/o surfacing, beded them with no change to the front vibrations. I'm curious as to how pad deposits can change so much with heat. The rotors on the outside look clean. I will look at the inboard later.
