“ST Speedtech Coilovers are made by KW, the leading brand worldwide for height adjustable coilover systems. In fact ST is owned by KW automotive. Just think of ST as KW’s little brother! What's the difference between KW coilovers and ST Coilovers? Four simple differences: Construction ST Speedtech Coilovers are constructed of high grade steel, and heavy galvanized for great rust protection. KW Coilovers are made from INOX stainless steel, which is 100% rust free.
