What is a linear spring rate?

A linear spring rate means that for every inch the spring is compressed, the force it exerts increases by a consistent amount. This provides predictable suspension behavior during driving.

What does the spring rate (N/mm) indicate?

The spring rate indicates how stiff the spring is. A higher N/mm value, like 100 N/mm, means the spring is stiffer and will resist compression more strongly than a spring with a lower rate.

What is the inner diameter of this spring?

This AST linear race spring has an inner diameter of 61mm, which is a common size for many coilover applications.

Product Details

AST is known for making performance suspension components. This linear race spring is designed for track use, offering a consistent spring rate for predictable handling. With a 100 N/mm rate, it's a solid choice for those looking to stiffen up their suspension for improved cornering performance.

This spring measures 140mm in length and has a 61mm inner diameter, making it compatible with many coilover setups. The linear rate means that as the spring is compressed, the force increases proportionally, which helps maintain tire contact with the road during aggressive driving. It's a well-built component that can make a notable difference in your vehicle's responsiveness on the track.
