I have lightweight magnesium rims on my 2000 C5, and was thinking of switching them at some point, either to black rims or possibly to chrome, but Im worried about the increase in rotating weight. Does anybody have a link to or a list of the weights of rims for c5 corvettes? Also, does anyone know where I can get lightweight rear magnesium rims for a y2k vette that are wider than 18x9.5?
