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

A linear spring rate means the spring's resistance to compression increases at a constant rate. This provides predictable and consistent suspension behavior, which is beneficial for performance driving and track use where precise control is important.

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 performance coilover systems, but it's always best to measure your existing spring or shock body to ensure compatibility.

What is the purpose of a 100mm length spring?

The 100mm length is a specific dimension for this spring, often chosen for custom suspension builds or when replacing springs in certain coilover applications. It's important to ensure this length works with your shock absorber's travel and overall suspension geometry.

About this part

Product Details

These are AST Linear Race Springs, measuring 100mm in length with a spring rate of 60 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is critical. The linear rate means the spring's resistance increases consistently as it's compressed, offering predictable handling characteristics.

Built for demanding use, these springs are a solid option for track day cars or custom suspension builds. The 61mm inner diameter is a common size for many coilover systems, making them a versatile choice for racers and tuners looking to fine-tune their vehicle's suspension setup. When selecting springs, matching the rate to your vehicle's weight and intended use is key for optimal performance and ride quality.
