What does a 280 N/mm spring rate mean for my car?

A 280 N/mm spring rate indicates that for every millimeter the spring is compressed, it will exert 280 Newtons of force. This is a relatively stiff rate, suitable for performance applications where precise control and reduced body roll are desired.

Can I mix and match these springs with different rates?

Yes, these springs are sold individually, allowing you to create a custom setup by combining different rates on the same axle or replacing a single spring if needed. Always ensure the rates are appropriate for your vehicle's balance and intended use.

What is the advantage of a linear spring rate?

Linear springs offer a predictable and consistent force increase as they compress. This makes suspension tuning more straightforward, as the relationship between suspension travel and spring force is direct and easy to calculate.

About this part

Product Details

Starting with a 280 N/mm spring rate, these AST Linear Race Springs are built for serious performance tuning. The 61mm inner diameter is a common size for many coilover setups, and the 100mm length offers a compact profile for suspension designers working with limited space.

These springs are designed for consistent performance under demanding conditions. The linear rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is crucial for fine-tuning suspension response, whether you're setting up a track car or a performance street vehicle. The well-built construction ensures they can handle the stresses of repeated compression and extension.

If you're rebuilding or customizing a coilover system and need a specific spring rate and diameter, these AST springs are a solid option. They are sold individually, allowing you to mix and match rates or replace a single worn spring.
