I think i know whats wrong now

Just so everyone is on the same page...

"Warped" is a term often used incorrectly to describe a rotor with excess pad deposit. This makes the surface of the rotor uneven, which is what causes the vibration. The scenario Boob gives of sitting on the brakes at a stop light after hard braking is excess pad deposit. The pad material basically continues to melt onto the hot rotor in one spot while you're stopped, and then you're left with a uneven portion of the rotor that can be extremely noticeable under braking.

Truly warped rotors are pretty much exclusive to track driving, although I'm sure there's some idiot that managed it on the street. But I think you'd have to be driving like a maniac to do that on the street...

Well, colour me stupid. I'm disappointed that I have imitation warped rotors then.

Maybe? I doubt it. It could just be my driving style, though I don't generally brake hard or sit on the brakes much.

Maybe it's just a combination of traffic and the warm temps out here? I dunno.

It's probably just me in the end.

hummm... id swap the pads and get those rotors turned. if it still persists, replace the rotors with aftermarkets (mr.jar's recommendations).
