  • Coil springs can be either "hot-coiled" or "cold-coiled". Hot Racing springs are cold-coiled and are wound from pre-heat treated spring wire stock. This produces a superior spring versus many other so-called performance springs that are "cold-coiled" from annealed "bundle stock, " then quenched and tempered after coiling. This inferior method produces a less accurate spring and can result in surface imperfections
