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.

Features

• Heat Treatment Manufacture (HTM) inner barrel technology enables thinner aluminum walls for reduced weight without compromising structural strength
• Includes an authentic SSR logo flat center cap and a high-durability air valve stem assembly

A wheel is the rim the tire mounts on; it bolts to the vehicle's hub, and its diameter, width, bolt pattern and offset set how the tire sits under the fender.
