wheel spacer bore concern

I just got my spacers and went to install. Amazon confirmed 106mm bore was proper size for my vehicle. However, I went to install and the fit the hub, but right against the inner face of the hub, the ID steps up for about 1/4 inch to 108mm, preventing the spacer from seating against the face of the hub. The step leaves a gap between spacer and hub face. Is this normal ??
Sorry to throw in a most likely beat to death topic, but I can't find the answer any where else

 

Definitely should sit flat. Look into Bora brand spacers. They were relatively inexpensive and worked well when I had them.

 

Thanks for the reply Whippersnapper02...
As a mechanically inclined fellah, I was 100% thinking the same. I will look into your suggestion.

 

Bora, not bra but feel free to look under a bra.

 

send back and get spacers from a reputable source not through Amazon

 

I tried the cheap Amazon spacers. KSP I think or something like that. Tolerated them almost a month then returned them as I couldn't take the shakes from 55-62 MPH anymore. Lesson learned. If I need more "poke" I'll get it with the wheels not spacers.

 

Plus mine caused a pretty gnarly rub at full lock in reverse.

 

This is the type of job where your goal shouldn’t be to save money. As others have mentioned, go with a good/known brand.
