16x7 OZ Ultraleggera's on an E30 ?tion

[geoffp]

so i bought those wheels for my 1988 325 sedan from tirerack, now initially tirerack told me i did NOT need to run hubcentric rings for these wheels. well turns out i do, when cruising on the highway you can feel the vibration.

so i find a company that sells hubcentric rings for the wheels, buy them, install them, no dice. they fit the car but not the wheel, i contact the company and they ask what the centerbore of the wheels is, well turns out they don't have rings to fit this size wheel.

any reccomendations? anyone know a place that might have the correct hubcentric rings for my wheels?? thanks a ton!!
