AST astAST-150-140-61

The AST linear race spring is a single 150 mm coil spring with a 140 N/mm rate and a 61 mm inner diameter, specified for coilover-style suspension to raise spring rate and influence ride height. Supplied individually, it offers tuners a way to stiffen corners and coordinate with damping choices; verify that your coilover spring seat is compatible with the 61 mm ID before installation.
