AST astAST-300-150-61

The AST Linear Race Spring is a single 300mm coil spring with a 150 N/mm linear rate and a 61mm inner diameter. Intended for coilover use, the higher linear rate supplies firmer support for aggressive setups while maintaining consistent compression behavior. The 61mm ID is compatible with standard 61mm spring perches and the single-unit sale makes it simple to tailor spring rates across a vehicle.
