Thanks for the link. Looking at a 2014 ZL1 brochure it lists a 5 spoke "bright" rim (the same as "polished" in the thread?), which according to the Registry are 11lb lighter vs the black which are also available on the SS. This of course doesn't match the actual test in the thread...so now I understand why folks issued the "ass-u-me"...comment. Is it possible that 2014 5 spokes are different from prior years? I wish the manufactureres would include such weights right in the brochures in the first place.
