Good call. Maybe if we were all SCCA racers, light wheels would be a must, but 99% of us here are using our cars to get from A to B and having a little fun in between.
Most of us also have a nice big turbo set up on our cars that laugh in the face of heavy wheels.
Heavy, +2 sized wheels only really mattered on my torqueless, 120hp Honda that I had 12 years back.
I put "quality construction and reputable manufacturer" ahead of "weight" in my search for aftermarket wheels.
