I'm re-starting my second HPDE season, and checking and double checking the car beforehand. I'd love feedback on a couple of issues:

1) I just swapped out the brake pads to Carbotech XP10's I used previously, bedded them, and after the swap, it feels like my rotors are warped. Didn't feel like that with stock pads. Are the rotors actually warped, or is it pad deposits, uneven brake pad contact from swapping pad positions, other issues?

2) While under there, I saw a small amount of grease leaking from the small side of both inner CV boots. Enough to fling and get some on the frame parallel with that axis of rotation, but no holes in the boots, clamps seem tight, doesn't seem like the amount of grease I've seen thrown from torn boots, no clicking noise when turning or otherwise. Replace boots, or wait for other symptoms, or? Car is lowered ~1.5" all around.

3) Last time at track (March?) on second day I had vibration, seemed like from the rear, above 100mph. I checked everything I could, thought it might have been unbalanced tire from a lost wheel weight. Once home, I changed wheels and it went away. Had track wheels rebalanced, didn't re-emerge in brief venture to 100mph. Wheel balance seem like the likely cause, and not CV joints, given they aren't making noise?

Thanks all....
