How dangerous are wheel spacers (1/4”) for oem rims?

Hey quick question. I bought 4 like new and true oem Mazda 17” rims for my 09 Elantra as my current oem Hyundai ones are pretty bent and vibrate. The Mazda rims have the same 5 x 114.3 and bore and other specs but the front brake calipers on the front are ever so slightly touching the inside face of the rim so I could not get them mounted because of that. But the shop suggested I buy 1/4” wheel spacers for the front to place the rims ever so slightly outward, but I’m kinda concerned that the wheel spacers might damage something? Am I over thinking this? It seems like a basic idea but would that affect handling, or put more wear on components ect? Has anyone ever used them and had success? I feel like the vibration is also causing wear but I can not justify the $130 per rim to fix the Hyundai rims, so I bought these Mazda rims as replacements. Thoughts? I’d really would like to use them lol, Thank you.
Edit I will be swapping over new 215/45 tires to these Mazda rims

Sadly, the offset is incorrect and I don't know myself so, I realize that this is of no information to you. However, I think this would be a very cool wheel on your car. :)
 
The 1/4”s scare me more than the 1 1/2” hubcentric I’m running on my frontier.
 
I’ll be honest I have no idea what I’m looking for here. I bought these 1/4” spacers at the zone but now I’m reading about hub centric and adapters, and rings ect.. on Hyundai’s where is the load on the studs or the center bore area or both lol? I can’t find hub centric with 64.1 bore and 114.3 in 1/4 inch..
I feel like it’s such a small amount that I could probably get away with using these, but from a safety and vibration standpoint would these cause more problems then they are worth? Somehow reviews are pretty positive for them. Can someone break this down for me please as I never had fitment issues on any one of my vehicles so this is all new for me.
thanks!

6mm isn't going to affect much. You can usually find a higher variation between OEM wheels.
This Hyundai has options from 15” steel wheels to 17” alloys with off set around 40? Does that sound correct?

it appears the Hyundai has a offset of 46mm while the Mazda is 50mm?

64.1 and 114.3 is pretty common and you'll find a lot of aftermarket wheel-anything in those specs.

Here's some H&R 10mm spacers with those specs.
 
6mm is fine. Up to 12mm is OK.
Most importantly is to get good spacers.
The issue with spacers and bearings is usually on the track where there are high loads. If you are not tracking your vehicle, go for it.
 
I believe spacers that have they own bolts and nuts are safer to use

Because you don't run the risk of the wheel coming off because you did not have enough threads on the bolt to secure the wheel on. Spacers are installed on the bolts of the hub and then the wheel is installed on the bolts of the spacers.

You have 2 set of bolts. It is not as installing a shim between the hub and the wheel

Part of installing any spacer is checking thread engagement. Longwr studs/bolts may be necessary. They're probably not at 5-7mm.

The bolt+on spacers are only available in large sizes (20mm+) and can really only be used with cars that use wheel bolts and/or wheels that have pockets in the hub.
