wheels to clear cayenne calipers without spacers

[audi5inline]

I have installed porsche cayenne calipers ZR18, i'm now running 18 inch rs6 rims ET45 with 15mm spacers.
I would like to get rid of the spacers because i have some small vibrations, are there any Audi wheels that will clear the calipers without spacers ?

Are your spacers hubcentric?

yes they are

I almost want to say that you need to get the wheels re balanced + alignment. Dont blame the vibration on the spacers.
