About H&R Springs

H&R Springs was founded in the late 1970s by Werner Heine and Heinz Remmen. The pair of them saw the need for improved suspension on the street and shared the belief that, with such, vehicles would have more control and better handling. Both Mr. H and Mr. R had years of professional and personal automotive experience. They used their technical know-how, driving experience, and suspension expertise to build superior quality springs that would create a new look in the automotive world with a “correct vehicle stance.” Mr. H and Mr. R’s commitment to producing a quality product allowed them to obtain TUV certification and the European performance spring market was subsequently born.
