-Your tires are worn around the edges because of uneven wear while cornering at high speeds. Lateral acceleration shifts the weight of the car to the edges.
-Rotors pulsating probably means that your rotors are warped. That happens when you overheat the steel from excessive hard braking. You can replace the rotors, but I've found that if you just machine the rotors and change the brake pads that will do the trick as well.
-It will "sound like a sewing machine rev up as it idles down." This is normal when on Track and Sport settings. That's the car functioning properly on its rev matching design. The idea is that when you take a corner, you have to slow down, but to save time you want to get out at the lowest gear possible and accelerate. To do so, as your car slows down the automatic transmission downshifts and revs matches to get you ready to accelerate. So if you're in the Track/Sport setting and slowing down (e.g, at a red light), it will downshift and rev match because it doesn't know that you're not taking a corner. Drive in Tour or Eco and it won't do that.
Your car was tracked. No doubt. Who cares? It's still under warranty if anything truly bad happens to it. You bought a used car. You should expect it to have wear. The previous owner drove it on a track. Who knows what else he/she did in it? Maybe someone died in it. Maybe he drove the 2200 miles butt naked. My point is you can lose sleep over what may have happened to your car...or you can let it go and just enjoy your car!
You have a beautiful car that if you replaced the tires and brakes then would look and feel brand new. Enjoy it and don't stress about it!
