I'm a newbe here, interested in a set of summer wheels for my soon to be new A3 TDI. Most every where I look I find wheels that look like they would work like fans, pushing or pulling air, and costing FE. Also these vendors / manufacturers / OEM's ( with the exception of Volvo - as seen here - thank you ecomodder ) refuse to post their wheel weights. I guess you are supposed to make your choice purely on the elusive criteria of esthetics.
Some how, it seems to me, a wheel maker should be encouraged to produce a line of light weight, aluminum, aerodynamic ( moon disk ? ) wheels. Would there not be a market ? I'm already standing in line.
