SSR Professor SP1R wheels adapt the legendary 5-spoke racing layout into a full reverse rim 3-piece modular construction engineered specifically for compact and mid-sized performance cars. Joining a precision center disc with spun aluminum rim shells, this design delivers a clean, deep-dish silhouette with maximized lip depth. Built using SSR’s advanced Semi-Solid Forging (SSF) technology, the SP1R offers superior structural rigidity and track-proven durability while maintaining a lightweight footprint that sharpens steering feedback.
