I am looking in to purchasing a set of Volk SF-Challenges for my G35 Coupe with Brembos. 19x8.5 / 19x9.5 wrapped with 245/35/19 275/35/19 Toyo T1s. The vendor said the rims will come with Hub Rings. I thought you didn't need hub rings if the rims are the proper offset. He said they are needed to reduce the highspeed vibration and that the hub on our wheels is smaller than the one on the rim. Is this true? What do you guys think looks better on a DG Coupe the RMC finished wheels or just Gunmetal?

 

I ran hubcentric rings on my GT-C's as well. It's there to prevent any high speed vibration.

RMC finish is hot
