The AST Linear Race spring is a single 80mm-length coilover spring with a 20 N/mm rate and 61mm inner diameter, sold individually for coilover or suspension tuning. Its linear rate and compact 80mm free length make it suitable where a precise, consistent spring rate and a 61mm seat ID are required, allowing builders to specify exact spring characteristics for custom suspension assemblies.
