5x114.3 Wheels on a 5x115 Car

Okay, so I made a bad but good impulse purchase this week and bought a brand new set of Gloss Black AMR wheels made for a Mustang. They’re 19x8.5, which im also assuming is a +30 offset. I test fit them (I used the FL rim as a test point) and they fit on the car. After doing some research, I find out that people have been installing 5x114.3 rims on our cars since 03-04, so clearly someone has found a way to have them work; Hubcentric Rings. I dug deeper into the hub bore for the rims and AMR apparently has their HB in 70.6-70.8. Our hub bore is apparently 70.5. Is there a set of Hubcentric rings I can buy for my car to have these rims fit without any serious issues? Any help is appreciated.

Heres some pics below.

I don't believe you'll find hubcentric rings that are that thin. And I'm not sure why people have always thought hubcentric rings "fix" a mismatch in bolt patterns. Hubcentric rings don't fix the additional stress applied to the wheel studs as a result of the off-center positioning of the studs and the mounting holes in the wheel.

Search for wobble lug nuts and buy some of those. They are intended for correcting the mismatch if you really want to run wheels with the wrong bolt pattern.

I guess I worded that wrong for the most part. I meant that they've been used since our cars came out to fix things like vibration and things related to that. I am going to invest in some wobble lug nuts as well before I go and have them installed. The wobble lugs might be the only thing I'd change if I can't find the hubcentric rings for the car. I totally worded that wrong though, apologies. I just want to mainly find both so I have a safe install of these rims, because I do like how they look so far on my car.

Just my honest opinion:
With over 50 years wrenching on cars, and 25 of that getting paid to do so, 10 of THAT being a tire/wheel/alignment specialist, MY OPINION IS, the mistake you are making is in your title. 114.3 does not equal 115 no matter what type of math you use. The tire/wheel assembly is the only connection you have to the road, it should be respected. Those are really fine looking wheels. Mount them to the vehicle wrong and they may not stay pretty long, not to mention your car and the folks around you when one of them fails. Please consider finding the correct bolt pattern, please.

Not shims, but couldn't the OP install a set of bonofide hubcentric billet spacer/adapters? With even just the wheel mocked up the fenders look well able to accomodate the 1"+/- added offset. I did such for my 5x5.25 to 5x115 wheels.
