You may just have some pad deposit. One of the instructors suggested hitting the rotors with some water the night before (to get a bit more abrasion on the rotors) and try to re-bed them in the morning when pads are cold to knock off the deposit.
I'm pretty sure warped, but I don't know what "pad deposit" is. I have 10k miles and it started at/after the track. Pedal and wheel vibration when braking...not very noticeable at 30mph, but very noticeable when braking at 60+. What symptoms do pad deposits show?

Also, this wasn't my second time at the track (I have a different track car, but decided to take this).
