What does a 100 N/mm spring rate mean for my car's handling?

A 100 N/mm spring rate is considered stiff. It means that for every millimeter the spring is compressed, it exerts 100 Newtons of force. This stiffness helps reduce body roll during cornering and can lead to a more responsive feel.

How do I know if this spring will fit my coilovers?

This spring has a 61mm inner diameter and is 130mm long. You should verify that your coilover shock bodies are designed to accept a 61mm ID spring and that the 130mm length is appropriate for your application, as coilover systems can vary.

Are these springs sold individually or as a set?

These AST Linear Race Springs are sold individually. If you need a pair for your vehicle, you will need to purchase two units.

Product Details

When you're setting up your suspension for track days or serious performance driving, the right spring rate is crucial for predictable handling. These AST Linear Race Springs are designed to give you a consistent and responsive feel on the track. They are built to work with coilover systems that accept a 61mm inner diameter spring.

This particular spring offers a 100 N/mm rate, which is a fairly stiff rate that helps reduce body roll during hard cornering and improves responsiveness to steering inputs. The 130mm length is a common size for many coilover applications, but it's always best to measure your existing springs or consult your coilover manufacturer's specifications to ensure compatibility. These springs are well-built for the demands of performance driving, providing a solid foundation for your suspension tuning.

If you're looking to fine-tune your coilover setup for a specific track condition or driving style, these linear springs offer a straightforward way to adjust your vehicle's ride and handling characteristics. Remember to always check your coilover system's compatibility for spring length, inner diameter, and maximum load before purchasing.
