In 1971 SSR released the first 3 piece wheel, the MK1. Aluminum wheels were in high demand and resulted in the creation of JWL (Japan Light Alloy Wheel) Certification in 1973. The Japanese Government incorporates this certification on aluminum wheels to improve quality and safety. JWL certification involves testing impact strength and endurance strength. SSR wheels are always put through JWL testing before they are used on the street or track. In 1981, a 3rd party statutory board the VIA (Vehicle Inspection Association) was created to verify JWL testing. Both the JWL and VIA logo are embossed into each and every SSR wheel representing dedication to quality control. SSR has always focused on manufacturing precise, lightweight, and strong wheels and will continue this tradition for years to come.
SSR was the first to creat 3-Piece wheels, helping to make the automotive aftermarket wheel industry what it is today. By utilizing high quality materials and precise techniques, SSR manufactures quality wheels like none other, leaving no room for compromise.
In 1991, SSR learned of an advanced technology known as Semi-Solid Forging (SSF). SSR is the only manufacturer in the world to produce SSF aluminum rims and continues to research ways to further develop SSF, creating reliable, durable, lightweight and exquisite wheels.
In order to deliver quality and reassurance, SSR's unique quality control of production surpasses JWL standards. SSR takes a different stance when supplying wheels to the race circuit. The race spec wheels are manufactured in the same essence as the commercialized wheels. This gives SSR direct feedback from the race circuit to further enhance the technology of the wheels. Time spent at the track and involvement with an array of motorsports has led to the technological developments that are embedded in every SSR wheel. SSR continues its involvement in motorsports with numerous victories in JGTC, Time Attack, Formula D, and D1GP.
