I recommend the Volk Gram Lights 57 (57 pro). They're brand new and pretty good. I don't know their weight yet, but they should be really light.

A great set of wheels (if you can find them, esp since most honda/acura owners don't know about them) are from the "Drift King". KEIOFFICE. I think the 15 in rims are like... 8lbs. I don't know of anyone that imports these here. You just have to go to Japan or have them shipped here by someone there. They lack on style.. but they're all about performance.
