AST astAST-150-260-61

The AST linear race spring is a single 150 mm coil spring with a 260 N/mm rate and a 61 mm inner diameter, specified for coilover-style suspension to substantially increase spring rate and alter ride height. Sold individually, it gives tuners an extreme-rate choice to pair with firm damping setups; verify the 61 mm inner diameter compatibility with your coilover assembly prior to fitting.
