If the search function ever gets working again :( , this has been discussed many times either in this section or the C5 sections. Basically, wagon wheels are the heaviest, forged and Z06 rims and mag rims are the lightest (19-20.X lb. range), and the cast '00+ style would fall in the middle. Sorry I don't have a more precise recollection.
