You can make a center cap puller by cutting one end of a metal coat hanger off about halfway between the hanger part and the end. Then just slightly bend the loose ends of it at about 90 deg. with a pair of pliers. Adjust the width of it by lining it up with the holes in the center cap then hold it at an angle, put the ends in the holes, push in and straighten it then pull the caps off. It's basically the same thing you will spend $35 for from Porsche. If you're unsure go to eBay or Suncoast and check out what they look like and you'll have a good idea of how to fashion it. It's very easy and I keep mine in my tool kit along with the locking key for the lugs.
