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

A linear spring rate means the force the spring exerts increases proportionally to how much it's compressed. This offers predictable suspension behavior, which is beneficial for tuning your car's handling for specific driving conditions or track setups.

How do I know if this spring will fit my coilovers?

This spring has a 61mm inner diameter and is 130mm long. You should verify these dimensions against the specifications for your existing coilover system or the manufacturer's recommended spring size.

Is this spring sold as a set?

No, this is a single spring. You will need to purchase the required number of springs separately to match your coilover setup, whether that's for one axle or all four corners.

Product Details

This is a single AST Linear Race Spring, measuring 130mm in length with a spring rate of 260 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is critical.

The linear spring rate means that as the spring is compressed, the force it exerts increases at a constant rate. This predictable behavior is essential for tuning suspension for specific track conditions or driving styles. The 130mm length and 61mm inner diameter are common dimensions for many coilover systems, allowing for straightforward integration when rebuilding or upgrading your suspension setup. AST is known for well-built suspension components, and these springs are made to handle the demands of spirited driving and track use.

When rebuilding or modifying your coilovers, ensuring you have the correct spring dimensions and rate is key to achieving the desired handling characteristics. Always refer to your coilover manufacturer's specifications to confirm compatibility with these springs.
