SSR Professor SP4 18x10.5 / -29 MD / 5x114.3 BP White Wheel (SPECIAL ORDER-NO CANCELLATION)

SSR Professor SP4 wheels refine classic 5-spoke geometry with sharp, angular spoke profiles and authentic 3-piece modular construction. Designed to deliver a sophisticated balance of motorsport performance and high-end street presence, the SP4 features a step-lip rim configuration paired with exposed perimeter pierce bolts. The cleanly sculpted spokes dip toward a recessed center hub, creating strong visual depth while maintaining an aggressive stance on luxury sedans, sports coupes, and track builds.
