I will second Kevins2 that fooling around with dead blow hammers, 2x4s, etc is a complete waste of time on KO wheels. Use a 6 lb lead hammer. Unless you are 250 lbs of pure muscle you shouldn't do any damage to your knock off spinners with a good lead hammer. Also be sure the weight of the car is on the wheels and the wheels on the ground when first loosening the spinners. Otherwise you are just beating your suspension components to bits. I have a Vette with KOs and my ERA. Used to put a piece of plywood on the ear of the Corvette spinner to protect the chrome when striking it with the little lead hammer supplied with the wheels - until I found one loosened up one day. No more of that - I got a 6 lb MT hammer and hammered them on - lead directly on chrome. I've never found a mark on any of my spinners from it.
