Thanks Rangerz, I'll double check the rotors, but these haven't been used for any track sessions yet (they're new two piece rotors). I was lucky to be warned before my first session out on the track not to use the brakes until they cooled down.

So as a follow up to this problem, now that it's fixed...

I replaced the front right hub thinking the slightly bent/off hub was causing a problem, and it didn't fix it. I reluctantly took the car to Watkins Glen on Tuesday for a HPDE and worked up to speed, making sure the brakes weren't going to be a problem. The shudder really wasn't that bad and seemed to actually almost disappear by the end of the day. Needless to say stopping from 120-140 to 60 over and over again has fixed my problem. lol It must have been a pretty good uneven layer of pad deposits. What threw me off though is that I did try re-bedding the pads and used the correct procedure and it didn't help one bit.

In conclusion, track day fixes cars. :D lol
