09 Charger rt wheels on a 66 plymouth fury

Not only running 5x114.3 on LX cars but doing it for 8 years and over 100,000 miles on thousands of them. This duscussion has been going on since 2004 and there are 2 sides, I personally say that less then .35mm isn't enough to make a difference, look at it on a ruler. That .35mm is what each lug needs to move for 114.3 vs 115.
I would figure out what hub center ring you need to make the hub tight on the wheel. They come in 100's of sizes and are not much money.
