What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring exerts increases at a constant rate as it's compressed. This provides predictable and consistent suspension response, which is beneficial for performance driving and track use.

What is the inner diameter of this spring?

This AST Linear Race Spring has an inner diameter of 61mm. This is a common size for many aftermarket coilover systems, but it's always best to verify your existing setup.

Is this spring sold as a set?

No, this AST Linear Race Spring is sold individually. If you are building or rebuilding a coilover system, you will need to purchase the appropriate number of springs for your application.

Product Details

This is a single AST Linear Race Spring, measuring 300mm in length with a spring rate of 100 N/mm and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is crucial.

The linear spring rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is favored in racing and track use for consistent handling and feedback. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and tuners looking to customize their suspension setup. The 300mm length offers a good balance for achieving desired ride height and suspension travel in many applications.

When building or rebuilding a coilover, selecting the right spring rate and dimensions is key to achieving the desired performance characteristics for your vehicle. This spring is a well-built component for those focused on optimizing their suspension for track days or spirited driving.
