What is a linear spring rate?

A linear spring rate means that the force the spring exerts increases proportionally to how much it is compressed. For every millimeter the spring is compressed, the force increases by a consistent amount, providing predictable suspension behavior.

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 compatibility with your specific coilover hardware.

What kind of vehicle is this spring best suited for?

This spring is designed for performance and racing applications. Its 180 N/mm rate is firm and best suited for track cars, race cars, or vehicles where precise suspension control and reduced body roll are prioritized.

Product Details

This is a single AST Linear Race Spring, measuring 130mm in length with a spring rate of 180 N/mm and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is crucial. They are a popular choice for track day cars and dedicated race vehicles that utilize coilover suspension systems.

The linear spring rate means that for every millimeter the spring is compressed, the force increases by a consistent amount. This predictable behavior is essential for tuning suspension dynamics, allowing for fine adjustments to handling and ride characteristics. The 61mm inner diameter is a common size for many coilover applications, making it a versatile option for builders and racers looking to upgrade or replace their existing springs.

When selecting springs, consider the overall weight of your vehicle and your intended use. A 180 N/mm rate offers a firm setup, suitable for reducing body roll and maintaining tire contact during aggressive cornering. Always ensure compatibility with your specific coilover body and mounting hardware before installation.
