What does a linear spring rate mean for my suspension?

A linear spring rate means that the force the spring exerts increases proportionally to how much it's compressed. This offers predictable handling and a consistent feel as the suspension works.

How do I know if this spring rate is right for my car?

The correct spring rate depends on your vehicle's weight, weight distribution, and how you plan to use it. For track use or a firmer ride, a higher rate like 95 N/mm might be suitable, but it's best to consult with a suspension specialist or research your specific application.

Do these springs come with any hardware?

These springs are sold individually and do not typically include additional hardware like perches or collars. You will need to ensure you have the necessary components for installation on your coilover system.

About this part

Product Details

These AST Linear Race Springs are built with a 61mm inner diameter and a spring rate of 95 Newtons per millimeter. The 250mm length makes them suitable for a variety of coilover applications where a specific suspension tuning is desired.

Constructed from high-tensile steel, these springs are designed to maintain their intended rate over time and under repeated stress. The linear spring rate means that for every millimeter the spring is compressed, it exerts the same amount of force, providing predictable suspension behavior. This makes them a popular choice for track-focused builds or for drivers seeking a firmer, more responsive feel from their suspension.

When selecting springs, it's important to match the rate to your vehicle's weight and intended use. These springs are sold individually, so you'll need to order the correct quantity for your vehicle's suspension setup.
