AST astAST-120-90-61

The AST Linear Race Spring is a single coil spring intended for race-style and adjustable suspension use, sized 120mm long with a 90 N/mm rate and a 61mm inner diameter. Supplied individually, it is a longer free-length spring choice for coilover or custom strut builds where a 90 N/mm rate helps firm up body control without shortening spring height.
