From the book "The Caine Mutiny". "When in danger or in doubt, run in circles scream and shout". Now if I can avoid the stampede of all the Chicken Little's screaming "The Sky is falling" them lets examine the situation. A doubler was required for racing so the lug nut would have a quarter inch of steel bearing instead of the factory 1/8 inch. Rules usually also called for a 5/8 lug that extended an inch out of the oversized lug nut. It's not my altered wheels that should concern you but rather the ones pressed/cast in some third world country. The situation reminds me of some seat belt mounts I have seen that are way beyond what it takes to kill whatever they are restraining. We build projects starting from chalk marks on the floor where some have gone over 330mph in a quarter mile, 200 plus in a circle, and 150 on dirt (Knoxville) and have lost numerous cars but zero drivers. Kind of verifies our judgement.
