I like the 16/17 combo because there are at least a few more tire choices that retain a proper balance in width (for purposes of balanced handling, as opposed to diameter for the TCS) without resulting in a larger overall diameter ( = taller gearing), which also adds unsprung weight.
Either way, consider Volk TE-37 (Dali has the best price Iíve found ). They probably are the lightest you will find for a given size, and by a large margin compared to all but a very few.
If you decide to use 16x8 and 17x9, look at the SSR Integral (Tire Rack has them). They are not as light as the TE-37, but still among the lightest available and very strong.
I'd like to hear what you decide and how you like them.
