Theirs a whole line up of Rays Engineering Volk Racing Wheels they are very expensive since they are probably one of the best with beautiful finishes. If you've ever owned any volk rim you should know they are hard to come by and the prices are very steep with Volk. The pricing doesn't tend to drop. I sold my volks for 1g they were the 18x8 3 piece GT-N's in Gunmetal, Chrome Plated lip with tires and I bought them for $2,700 removal 3 piece. They included tire covers, volk stem caps, volk tuner lugs. I would spend around $2,500-$3,000 for a good set of Volks. If you get Volk remember some of the Volk wheels do not come with center cap. Volk center caps range from $30-$50 for one and unless you have a great hookup the prices don't go down. Look around some people have better hook ups then shops if the timing is right.
What style rim you prefer on getting? Their bronze and gunmetal finishes are amazing in a 3 piece style but that's just my taste.
