AST Linear Race Springs - 250mm Length x 40 N/mm Rate x 61mm ID - Single

If you're building or rebuilding a performance suspension setup, choosing the right coilover springs is key to dialing in your vehicle's handling. These linear race springs from AST are designed for serious track use, offering a consistent spring rate throughout their travel. The 40 N/mm rate provides a firm, responsive feel, which is crucial for maintaining control during aggressive driving maneuvers like cornering and braking.

These springs measure 250mm in length and have a 61mm inner diameter, making them compatible with many coilover systems that use these common dimensions. The linear rate means that for every millimeter the spring is compressed, it exerts the same amount of force. This predictability is highly valued by racers and serious track enthusiasts because it allows for more precise tuning of suspension geometry and predictable vehicle behavior. They are well-built for the demands of racing and are a solid option for anyone looking to fine-tune their suspension for optimal performance.
