My new wheels won’t fit

Would you use spacers even if it go down the 1/4 mile?
I have but my 60ft was in the 2.4zone,lol. I have even used adapters with a 340car;
you just have to add checking them, to your regularly scheduled maintenance program. Whatever you use has to span the cavities in the back of the mounting surface, I mean that's just common sense. I used vintage Ansen-Sprint type wheels, designed for 4.5 bolt-circle,so are not slotted, and which don't have cavities, and do use open-ended shank-drive nuts, and I installed screw-in long studs; So big hard washers worked for me.
