The "rust belt" looks thicker than I have seen. I don't think you have warped rotors - easy enough to check - gently go on the brakes and if the steering wheel shakes, chances are one or more are warped.

I highly doubt one trip to wig would result in a warped rotor.
I would start by replacing the pads on all 4 corners.

I may have made the mistake of putting the e-brake on after one of the session runs (which I've read is not a good thing to do).

I'll get the car up on stands this week and put a magnetic base gauge on the rotors.

If you put the ebrake on there is a good chance you did some damage. The application of the ebrake does not allow the rotor to cool evenly resulting in warping. Common mistake the track...... Fortunately not too expensive to fix.

I get that uneven wiping when driving on the street sometimes. I wouldn't worry about it. Check it again after a day at the track.

You may need to consider if you have the right pads in the rear. The contact looks perfectly normal except it using only 9 tenths of the disc diameter. My money is on these pads being for a Carrera. It's amazing what some owners do to save $ whilst keeping a car roadworthy enough for sale purposes. Did you buy the car new? I'd do as TT surgeon says....replace the pads.
