i had to use a grinder and cut the lip off of the wheel around the hub hole thingy to get a honda steelie off of a mk2 once. still had to hammer the shit out of it to get it off. i wanna say honda hubs are a few mm smaller in diameter so its a real tight fit.
Yeah, and the kia wheels have an even smaller inside diameter than the hondas. I'll post some pix when I get back to the car. It's fuckin' stupid. Looks like my grease caps have a foreskin of smushed kia wheel material. It's been months and nothing's worked. Turns out my cheap-ass compressor won't run my air chisel, either, so I'm probably going to have to use my diamond bits and a rotary tool to cut the wheels off.
