If the wheel is not hub centric (missing hub rings), 90% of the time you will get a vibration especially on lower profile tires and stiffer suspension. When a wheel is not hub-centric, the wheel is relying on the lug bolts to be the center axis. This is NOT the truest part of the hub assembly. The HUB itself is. If the wheel is not spinning "true" cause it is relying on the bolt pattern to be true, it will translate into some sort of vibration even if the wheel/tire is perfectly roadforced balanced.
HUB CENTRICS, is the NUMBER ONE factor for "smoothness" on a vehicle when it comes to wheels and tires. Roadforce balancing is a close second.
Anyway my bet is if you are missing hub rings, then that is your first problem.
I believe most Volk wheels use a 73mm centerbore. So you will need a hub ring with a 73mm (O.D.- outside diameter) with a 67.1 (I.D.-inside diameter). Now keep in mind, not all hub ring manufacturers make rings exactly the same. It's hard to explain if you have never seen a hub ring but some have bigger flanges for different bevels on wheels. I would order rings from someone that has delt with Volk wheels and knows exactly which type fit.
