SSR Wheels Professor SP6 Under - Underhead x Center Lock Style
Underhead Disc Assembly with Center Lock Style Aesthetics
SSR Wheels Professor SP6 Under combines an underhead disc assembly with a CLS (Center Lock Style) center cap package, creating a powerful 5-spoke wheel that has become a benchmark in Japanese sports tuning. The result is a wheel that communicates motorsport identity without sacrificing the design refinement expected of the Professor line.
Underhead Construction
The underhead assembly positions the disc below the rim line, creating a recessed center face that deepens the visual impact of each spoke. Combined with the CLS center cap - which replicates the appearance of a center-lock racing wheel - the SP6 Under achieves an aesthetic that sits at the intersection of competition and street prestige.
Professor SP Line
SSR Wheels Professor SP series is designed for drivers who demand both visual character and functional performance from a 3-piece wheel. The SP6 Under adds a distinctive visual signature to the series through its underhead configuration - a design approach uncommon in the broader market and immediately identifiable to those familiar with Japanese performance culture.
Finish and Sizing
SSR Wheels Professor SP6 Under is available in multiple finishes suited to modern sports and luxury platforms.
