Are you talking about the Bremmer Kraft BR02? One is chrome plated and one isn't. The chrome plated one will be about a pound or so more in weight due to the added plating. If you go to the bottom of the description and click on closeup/detail, then click on full screen photo, you'll see the difference between the shiny silver and the chrome plating. I don't know what a "Mach Lip" is either, maybe a slightly different sheen/paint for contrast? It looks the same to me. Same wheel, one painted bright, one chrome plated. Anyway, it seems like you made the right choice. I like those too. Nice look!
