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.
- Heat Treatment Manufacture (HTM) inner barrel technology enables thinner aluminum walls for reduced weight without compromising structural strength
- Offered in four disk variations (HP, MD, NR, SL) to clear oversized multi-piston big brake kits or maximize rim lip depth
- Fully customizable offsets down to 1mm increments alongside wide custom PCD bolt pattern availability
- Includes an authentic SSR logo flat center cap and a high-durability air valve stem assembly
