SSR Professor SP1R 17x9.5 -29 MD 5/114.3 Black Wheel (SPECIAL ORDER/NO CANCEL)

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.

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.
