AST astAST-150-240-61

The AST linear race spring is a single 150 mm coil spring with a 240 N/mm rate and a 61 mm inner diameter, intended for coilover-style suspension to raise spring rate and modify ride height. Supplied individually, it provides a very firm spring option for matching heavy damping or specific handling goals; confirm that the 61 mm inner diameter fits your coilover spring seat before installation.
