SSR Professor SP1 wheels represent an enduring legend in Japanese wheel design, featuring a timeless, bold 5-spoke layout paired with authentic 3-piece modular construction. Engineered with a cast aluminum center disk joined to spun outer and inner rim shells, this wheel delivers structural integrity, exceptional sizing flexibility, and classic GT-racing heritage. The deep-set center face, step-lip profile, and perimeter pierce bolts create a muscular, aggressive stance that complements performance coupes, sports sedans, and widebody builds.

Features

• Manufactured using Heat Treatment Manufacture (HTM) technology on the inner barrel shell to optimize strength while minimizing material mass
• Includes an authentic SSR Professor logo center cap and a high-durability aluminum air valve stem assembly
• Precision offset customization down to 1mm increments across a wide selection of custom PCD bolt patterns

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.
