The RS is built around the lip. Every design sits a deeply concave face behind a wide, flat barrel that steps out to a prominent machined lip, giving real visual mass at the rim edge. Within that, the series splits into two families — a clean open five-spoke and a Y-branching mesh — so you choose the level of face detail without leaving the retro-race character. There's no exposed hardware; the proportions carry the heritage on their own. It belongs on something with a bit of history, where the wheel should reference genuine motorsport rather than imitate it.
