I used regular chrome mag style lug nuts with a normal socket and the first one I put on the socket wedged into the hole and I didn't think I was ever gonna get it back out, actually nicked up the wheel a bit but finally got it back out. It realy ticked me off too that it was a brand new wheel, but oh well, live and learn. When I ordered the wheels, the guy from Summit Racing actually told me there was a note in the puter about the socket being tight in the lug nut hole, but I figured a regular 12-point socket instead of an impact socket would fit, but it didn't. Have to use a spark plug socket. Good luck with your's if you buy them, they are pretty nice wheels for the money!
