There have been several posts from folks asking about the weight of these rims but nobody has put one on a scale that I've seen. The cool thing about these is that they might end up as some kind of collectors' item someday. Factory performance options usually get that way once they haven't been produced for a long time. I assume that they are heavier than a lot of other rims in this price range but you know that they will be quality.
Which factory steel rims do you mean? The ones on the base model?
The factory sport rim and tire we know weigh 35.75# each from another post with photo of wheel on scale. We can guess that the tire weighs about 18#.
How can the color be changed?
If you are interested in rim upgrades, there are hundreds of choices in the aftermarket. You just pick your price range and colors and sizes!
(As for Enkei, they make some very light rims--check out the RPF 1 at 9.5# for the 15" and just 15# for the 17" (
