What is the spring rate of this AST spring?

This AST Linear Race Spring has a spring rate of 180 Newtons per millimeter (N/mm). This indicates how much force is required to compress the spring by a certain distance.

What does 'linear' mean for a spring rate?

A linear spring rate means that the force exerted by the spring increases at a constant rate as it is compressed. This provides predictable suspension behavior, which is beneficial for performance tuning.

What is the inner diameter of this spring?

The inner diameter of this AST spring is 61mm. This is a common size for many coilover applications, but it's always best to verify compatibility with your specific setup.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring with a 100mm length, a spring rate of 180 Newtons per millimeter, and a 61mm inner diameter. These springs are built for performance applications where consistent spring rates are crucial.

The linear spring design means that as the spring is compressed, the force it exerts increases at a constant rate. This predictable behavior is important for tuning suspension response, especially in racing or track day setups. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for custom builds or replacements.
