i just swapped my winter wheels out and lowered my car. anyways i get vibrations from about 60-70mph but not <60 or >70mph. i am missing one hub ring so i am guessing that to be the culprit but the no vibrations >70 confuses me. anyways do you think its:

balancing, alignment, or the hub rings?

 

Get a hubcentric ring. It should solve the problem. I forgot to put mine on a few years back and I had the same problem.

 

yeah thats what i figured/hoped. i ordered some a couple days ago hopefully they'll get in today.

 

Be careful, I believe I bent up the centercore of 3 of my 18's b/c the dealer forgot to to put back the hubcentric rings. I brought the 3 rims to Wheels America to see if they can repair and they told me it's unrepairable. With the centercore bent, you'll not be able to see. On that note, always make sure the hubcentric ring is in place b/4 putting your wheels back on.

 

yeah i picked em up and putting on the 1 missing one seems to have helped out much. ill wait and see as i need an alignment if thats part of the issue as well. feels much more solid though after the ring, of course thats probably all in my head

 

Alignment has nothing to do with vibration.
