Hub Rings??

Hey all,

So my rims came in finally, and now I am waiting on tires..

I got sbp centerlines and the center hup cut out is larger then the hub on my car...

My rim shop said they didnt have any center hub spacers that fit my rims (roughly 69 mm?).

Is it important to have the spacers?
Or just tighten down the rims carefully?

thanks!
