The AST Linear Race Spring is a single 300mm coil spring with a 110 N/mm linear rate and a 61mm inner diameter. Intended for coilover applications, it provides a predictable linear rate useful when dialing suspension behavior. The 61mm ID matches standard 61mm spring perches and the single-piece supply lets tuners select exact rates for front or rear setups.
