Brakes juddering

[admu]

I was lazy and did not drive the car right after washing it . I then parked the car in the garage and was gone for a week. When I came back, the brakes were juddering. Initially, I thought it wasn't a big deal. I'll just drive it around and the rust will be wiped away by the pads. The intensity diminished the first couple days of city driving (slow). Then it stayed the same. I tried highway driving (high speed braking), I applied firm pressure, light pressure. No change. Brake still juddering. Did I cause permanent damage to my brakes? Or am I just not doing the right technique to get rid of this vibration? Help please.

I'm glad we are discussing brakes for track use because I need help in this dept.
I tried a few pads on my e36 M3 several years ago and found PFC 11 worked well for my use. Sebring is brutal on brakes because of its long straights and with the E36's smallish pads, some of the ones I tried melted and caused pad transfer. PFC 11 performed well.
I checked out PFC if they have 11s available for the Emira and found no size available so I'm now on the hunt. Thank you for all the recommendations. And keep them coming please.

I like PFC 11s alot and as you said they weren't available for the Emira. I've been running PFC 15's and they're similar with less initial torque, but similar linear torque/temp and great release characteristics. I was running PFC 15s in the front and 08 in the rear when on the iron setup.

I've got an extra set of PFC 15s for the front that I can sell if you're interested in trying.
