Use ET lug nuts to gain some tread engagement. You will have to drill your wheel seat with a 6mm or 15/64 bit to make clearance fort the extented portion of the shank.
I was only getting 5 or 6 in the back. I bought new studs from Classic Alfa and just did the rears over the weekend with new black lugs from RockAuto. Feel much better and safer now. I finished cutting the old ones off and unhooked the top e brake and was able to slide the new ones into the e-brake hole and tap the new ones in place.
