Here's how the 164 may look with different sets of wheels. Top left is original equipment (for Europe) 16-inch Speedline alloys. Great choice from the factory - smart and well-chosen, they are the same ones that dress my Q4 and I've no plans to change them. I admit that I had toyed around with the thought, so I superimposed some other wheels on the 164. Two of the other three sets are Alfa 156 original equipment 17-inchers that also fit the 164 (166 wheels, by the way, won't fit because they have a different bolt pattern). On the bottom right are aggressive 17-inch Zender Milanos, with very similar design to the original Speedlines. If I do upgrade I would go for the Zenders.
