What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring exerts increases proportionally to how much it's compressed. This offers predictable suspension behavior, which is beneficial for tuning and performance driving.

What is the typical application for a 160 N/mm spring rate?

A 160 N/mm spring rate is considered relatively stiff. It's often chosen for performance-oriented vehicles, track use, or vehicles that carry significant loads, as it provides a more controlled ride and sharper handling.

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 important to verify it matches your specific application.

Product Details

If you're rebuilding your coilovers or looking to fine-tune your suspension setup, these AST Linear Race Springs are a solid option. They offer a 100mm length, a 160 N/mm spring rate, and a 61mm inner diameter, designed to work with many coilover systems where these dimensions are specified.

Linear rate springs like these mean the force increases consistently as the spring is compressed. This predictability is key for performance driving, as it allows for more precise suspension tuning. The 160 N/mm rate is on the stiffer side, often chosen for track use or for vehicles carrying extra weight, providing a more controlled ride and improved handling response. The 61mm inner diameter is a common size for many aftermarket coilover applications, making it a versatile choice.

When installing these springs, ensure you have the correct spring compressors and safety equipment. It's always a good idea to refer to your coilover manufacturer's specific instructions for proper installation and any recommended hardware.
