What does a 190 N/mm spring rate mean for my car?

A 190 N/mm spring rate indicates how much force is required to compress the spring by one millimeter. This rate is generally considered firm and is often used in performance or racing applications to reduce body roll and improve handling response.

What is the advantage of a linear spring rate?

Linear springs offer a consistent rate of force increase as they are compressed. This predictability makes suspension tuning more straightforward and allows drivers to better understand how the suspension will react under different loads.

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 perch or shock body to ensure compatibility.

About this part

Product Details

Starting with a 190 N/mm spring rate and a 100mm length, these AST Linear Race Springs are built for performance applications where precise suspension control is key. The 61mm inner diameter is a common size for many performance coilovers, making them a versatile option for builders and racers looking to fine-tune their setup. These springs are designed to provide a consistent and predictable response under load, which is crucial for maintaining stability during aggressive driving or track use.

Constructed from high-tensile steel, these springs are made to withstand the rigors of demanding use without losing their intended spring rate. The linear design means that for every millimeter the spring is compressed, it exerts a proportional amount of force, offering a straightforward and understandable spring behavior. This predictability helps in setting up suspension geometry and allows drivers to feel more connected to the road or track.

When rebuilding or upgrading your coilover system, choosing the right spring rate is essential for achieving the desired handling characteristics. These AST springs offer a solid option for those seeking a specific rate to match their vehicle's weight and intended use, whether for track days, autocross, or spirited street driving.
