AST astAST-150-220-61

The AST linear race spring is a single 150 mm coil spring with a 220 N/mm rate and a 61 mm inner diameter, designed for coilover-style suspension to significantly raise spring rate and lower ride height where needed. Sold individually, it enables precise selection of high spring rates to match aggressive damper calibration; ensure the 61 mm inner diameter matches your coilover assembly before ordering.
