AST astAST-150-90-61

The AST linear race spring is a single 150 mm coil spring with a 90 N/mm rate and a 61 mm inner diameter, designed for coilover-style suspension to change spring rate and ride height. Sold individually, it allows selection of a firmer spring rate to suit heavier loads or more aggressive damping; confirm your coilover spring seat matches the 61 mm ID before purchase.
