SSR Professor SP6 wheels revive the timeless 5-spoke motorsport silhouette with an aggressive modern edge and authentic 3-piece modular construction. Engineered with an underhead assembly structure—where the center disc is mounted from the inner side—the SP6 maximizes outer rim lip depth and showcases a mirror-polished lip surface. Highlighting its track heritage, the SP6 introduces SSR’s signature CLS (Center Lock Style) multi-layered cap system, delivering an authentic F1 and Super GT mechanical appearance. Combining ultra-durable heat-treated rim barrels with bold 5-spoke geometry, the SP6 offers an uncompromising balance of race-bred strength, deep-dish profile, and tailored fitments for high-performance sports cars and luxury sedans.
