I've searched and I've put Miata wheels on a CRX before. I know the center bore is off, do I use hub centric spacers to avoid boring them out more? I can't remember what I did...lol

 

Mata hub is smaller so having a machinist machine out the bore is the only way safely.

 

Apparently nothing if the hub is smaller on the Miata.

 

Well I did have them on there perfectly fine without boring out the centers. Considered it then went and got spacers or rings or soemthing that I now can't remember and it worked fine.

Maybe it was a disaster waiting to happen who knows it was years ago but I even tracked it once and it was fine.
