Did you perchance find a graceful way to deal with the pins on the rear brakes? I also put in some track pads right around 1,000 miles and went to the track, and getting the rear pins seated was the most annoying part. All my punches are too long to be able to move a small hammer on the inside of the wheel, so I used a screwdriver bit from my drill which is shorter, but I also managed to hit my knuckles a few times with the hammer when doing that. Eventually managed to do it with the driver bit and using a small hammer sideways.
