I'd take them either way but might as well keep them all together. Let me know your price. Dealer gave me a great quote this week, they are really open to negotiating on sets these days. Markup on tires and wheels is ridiculous (like jewelry) and I've found in this economy they are willing to negotiate pretty well because they need the sale. Still crazy expensive though compared to high-end aftermarket. And the wheels themselves are much heavier than aftermarket in same price range in many cases.
Let me know. email@example.com
