Just a little clarification: I looked at your pics (thanks Spyfunkr!) but the 4th gen. Hondas are definitely different than the 86-89 versions. My rotors do not bolt on, rather are held onto the hub by 2 screws. Don't worry...if/when I do change the stud, I'm going to change all of them with new Honda lugs and studs. Which brings me back to my original problem--- I'm still not sure if I can get the old ones out and the new ones in!!
