SSR Wheels

SSR Wheels, formerly known as Speed Star Racing Wheels, is a Japanese wheel manufacturer headquartered in Osaka. The brand produces wheels for motorsport, performance vehicles, and the specialist aftermarket, and is particularly associated with lightweight multi-piece, cast, forged, and semi-solid-forged designs. Its history began in 1971, when Speed Star Co., Ltd. introduced the MK-I, a three-piece wheel that is widely credited with being among the first, and often described as the first, production three-piece wheels ever made. This early focus on motorsport-oriented construction helped establish SSR as a distinctive Japanese performance-wheel producer rather than a general-purpose automotive supplier. The company’s influence extended beyond product design. SSR contributed to the development of Japan’s JWL wheel-safety standard in 1973 and helped establish the VIA third-party certification system in 1981. These standards operate under the regulatory framework of Japan’s Ministry of Land, Infrastructure, Transport and Tourism and became important reference points for wheel strength and quality compliance in the Japanese market. SSR subsequently broadened its technical portfolio from three-piece wheels to two-piece, cast, forged, and hybrid constructions. International expansion began with the opening of an overseas sales office in Los Angeles in 1985. The company later became known for its work with semi-solid forging, or SSF, a manufacturing process it adopted for alloy wheels in 1991 and subsequently patented. A new factory in Nara opened in 1993. In 2000, SSR introduced the Type-C, promoted at the time as the lightest wheel available for its size category. In 2002, it developed a two-piece hybrid wheel combining semi-solid forging with heat treatment. These developments reinforced the brand’s positioning around weight reduction, structural performance, technical manufacturing, and racing-derived design. SSR has maintained a substantial motorsport association. Its wheels have been used by factory-backed and customer teams connected with Honda, Toyota, and Nissan, as well as by SSR’s own Speed Star Racing operation. The company and its sponsored teams competed in Japanese single-seater racing, endurance racing, touring cars, Japanese Grand Touring Championship events, Super GT, Formula 1 supply activities, and drifting. Notable activities include Speed Star Racing’s Formula 2000 and Formula Two participation, wheel supply to Leyton House Racing’s March 881 in Formula One during 1988, endurance victories with a BMW M1, and long-running involvement with Hasemi Motorsport and other Japanese racing organizations. The brand is also strongly connected to enthusiast culture. SSR aftermarket wheels are used on sports compacts, Japanese import cars, show cars, drift cars, and circuit vehicles. Its catalog has included GT, Professor, REINER, MINERVA, Formula, SPEED STAR, EXECUTOR, ABELA, Blikker, and DEVIDE lines. The company was acquired by Tanabe Co., Ltd. in 2005, bringing SSR into the Tanabe group while preserving its identity as a specialist wheel brand. SSR’s present identity remains centered on Japanese engineering, motorsport heritage, lightweight construction, fitment variety, and premium enthusiast applications.

SSR Wheels originated in 1971 under Speed Star Co., Ltd., which launched Speed Star Racing Wheels to manufacture specialized three-piece wheels. The company’s early MK-I design became central to its reputation and is widely credited as an early, and frequently identified as the first, three-piece wheel. Three-piece construction allowed the wheel center, rim sections, and related components to be designed and serviced with greater flexibility than a conventional one-piece wheel, making the format especially useful in performance and racing applications. SSR became involved in the development of Japanese wheel-quality regulation during the 1970s and 1980s. It helped motivate the creation of the JWL standard in 1973 and contributed to the establishment of the VIA third-party certification system in 1981. These systems provided methods for evaluating wheel quality and safety in Japan and are regulated within the framework of the Ministry of Land, Infrastructure, Transport and Tourism. This technical and regulatory involvement helped associate SSR with formal wheel engineering standards rather than treating the company solely as a styling brand. During the following decades, SSR expanded its product technologies. In addition to three-piece wheels, it introduced two-piece designs and developed both cast and forged products. The company opened an international sales office in Los Angeles in 1985, reflecting the growing overseas market for Japanese performance wheels. In 1991, SSR became the first and, at that time, only alloy-wheel manufacturer reported to be using semi-solid forging for its wheels. It later patented the process. A Nara factory opened in 1993, supporting the company’s manufacturing activities in Japan. The brand’s technical development continued with the Type-C in 2000, which was described as the lightest wheel available for its size at the time. In 2002, SSR developed a two-piece hybrid wheel that combined semi-solid forging and heat treatment. These developments reflected the company’s recurring engineering priorities: reducing unsprung mass, improving strength, and offering construction formats suited to racing and serious aftermarket use. Motorsport has been a major part of SSR’s historical identity. The company operated Speed Star Racing, which entered Japan’s leading single-seater categories. In the 1977 All-Japan Formula 2000 championship, Kunimitsu Takahashi won three races and finished second in the championship. The team later competed in the 1978 and 1979 All-Japan Formula Two championships and continued into the 1980s, including the renamed All-Japan Formula 3000 series. Drivers associated with the operation included Takahashi, Naohiro Fujita, Motoharu Kurosawa, Masahiro Hasemi, Jeff Krosnoff, and Yoshiyasu Tachi. SSR also supplied wheels to Leyton House Racing for its March 881 during the 1988 Formula One season. In endurance racing, Speed Star Wheel Racing entered a BMW M1 in Japanese events. The car achieved a series of notable results, including victory in the 1979 Group C Suzuka 500 miles, the 1980 Japanese Endurance Championship, several Fuji endurance races, and multiple 1982 victories after being rebuilt for Group 5 regulations. It also finished fourth overall at the 1982 World Endurance Championship round at Mount Fuji. The car was retired from competition in 1984 and later used for historic racing and promotional appearances. SSR-supported touring-car activity included Hasemi Motorsport’s Nissan Skyline programs. In the Japanese Touring Car Championship, the SSR-equipped team won the JTC-1 championship in 1989, 1991, and 1992. In the All Japan Grand Touring Car Championship, Hasemi Motorsport competed in the GT500 category from 1994 through 2000 and achieved runner-up championship results in 1994 and 1995. The team also raced an SSR-sponsored Nissan Skyline RS Silhouette in Japanese Super Silhouette competition, winning two races in 1982 and five in 1983. The company continued to support sports-car and drifting programs. Team Kunimitsu used SSR-sponsored Honda machinery at the 1996 24 Hours of Le Mans, finishing third in the LMGT2 class and sixteenth overall. SSR later supported teams in Super GT, including Team Mugen, Autobacs Racing Team Aguri, Team Real Racing, and Team Kunimitsu. The supported teams recorded Super GT title successes, including Team Mugen’s 2013 GT300 championship and Team Kunimitsu’s 2018 and 2020 GT500 championships. In drifting, SSR sponsored Chris Forsberg and Forsberg Racing in Formula Drift from 2006 through 2021. Tanabe Co., Ltd. acquired SSR in 2005. Under Tanabe ownership, SSR has continued as a specialist wheel brand with product families spanning GT, Professor, REINER, MINERVA, Formula, SPEED STAR, EXECUTOR, ABELA, Blikker, and DEVIDE. Its reputation remains based on Japanese production heritage, racing involvement, advanced wheel manufacturing, and strong recognition among performance-car and import-car enthusiasts.
