I'd like to have 8 lug wheels but I have a set of 6 on 5.5 I'd like to use.....I'm thinking about drilling them for 12 lug. The back side is flat, the center is really thick....I don't see what the big deal would be. Instead of starting with 6 lug D60 hubs, I could get the blanks instead. The rear is all custom any way...What do you think? It would be a 12 on 5.5.
