What does a linear spring rate mean for my car's handling?

A linear spring rate means the spring's stiffness increases at a constant rate as it compresses. This offers predictable suspension behavior, which is beneficial for performance driving and track use where consistent feedback is important.

What is the inner diameter and length of this spring?

This AST Linear Race Spring has an inner diameter of 61mm and a length of 150mm. These dimensions are common for many coilover applications, but it's always best to verify compatibility with your specific setup.

Is this spring suitable for daily driving?

While this spring is designed for performance and track use, its 70 N/mm rate can be suitable for daily driving if you prefer a firmer ride and improved handling response. However, it will be noticeably stiffer than stock suspension.
