Founded in the early 80’s in Southern California under the company name of Suspension Techniques. ST positioned itself in the market due to innovative products, utilizing quality materials, modern technologies, and streamline processes to become a recognised brand by many enthusiasts and tuners and became a household name in the tuning scene in the 80's and 90's.
In 2005 ST was acquired by KW automotive GmbH, bringing a technological transformation to take ST to a whole new level, not only increasing its application range coverage but adding the innovative ST Coilover program, which was modelled after a galvanized KW Variant 1 coilover design. With this influx of KW’s leading technology, staff, and engineering base ST boasts one of the largest application ranges of any suspension manufacturer in North America
