Hi Bin on the search for suitable wheel nuts for my new rims stumbled on different coloured wheel nuts made of aluminum. had already one of WORK and RAYS in his hand. They weigh almost nothing, but are expensive:http://www.workwheelsusa.com/news-post.php?article=59 Do these things what? Is this “aircraft” aluminum better for a wheel screw than steel?
