What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring exerts increases at a constant rate as it's compressed. This provides predictable handling and makes it easier to tune your suspension for specific driving conditions.

How do I know if this 61mm ID spring will fit my coilover?

The 61mm inner diameter is a common size for many performance coilover assemblies. It's best to measure the inner diameter of your existing springs or check your coilover manufacturer's specifications to ensure compatibility.

What is the advantage of a 50 N/mm spring rate?

A 50 N/mm spring rate is firmer than most stock springs, which can lead to improved body control and reduced body roll during cornering. This makes it suitable for performance driving and track applications where precise handling is desired.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring with a 200mm length, a spring rate of 50 Newtons per millimeter, and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is needed.

The linear spring rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is crucial for tuning suspension response, allowing for consistent handling during spirited driving or track use. The 61mm inner diameter is a common size for many performance coilover systems, making it a versatile option for builders and racers looking to customize their setup.

When building or rebuilding coilovers, selecting the right spring rate is key to achieving the desired ride and handling characteristics. This 50 N/mm rate offers a firmer feel than stock springs, which can improve body control and reduce roll during cornering.
