What does a linear spring rate mean?

A linear spring rate means that for every unit of distance the spring is compressed or extended, it exerts a proportional amount of force. This results in predictable suspension behavior, which is beneficial for tuning and consistent handling.

What is the advantage of a 61mm inner diameter spring?

A 61mm inner diameter is a common size for performance coilovers. This specific diameter allows the spring to fit correctly onto the shock body and perch of compatible coilover systems, ensuring proper function and alignment.

What is the typical application for these springs?

These springs are typically used in performance and racing applications where precise suspension tuning is required. They are designed to work with compatible coilover systems, often requiring matching damping adjustments for optimal performance.

Product Details

Starting with a 61mm inner diameter and a spring rate of 210 Newtons per millimeter, these AST Linear Race Springs are built for performance applications where precise suspension control is key. The 80mm length is a specific dimension that works with certain coilover setups, offering a compact profile for tight spaces.

These springs are constructed from high-tensile steel, a well-built material chosen for its ability to withstand repeated compression and extension cycles without losing its intended spring rate. The linear design means that for every millimeter the spring is compressed, it exerts the same amount of force, providing predictable suspension behavior. This predictability is crucial for tuning a vehicle's handling, especially during spirited driving or track use where consistent feedback from the suspension is needed.

When considering a spring swap, remember that changing the spring rate will alter how your suspension reacts to bumps and body roll. It's often best to pair these with appropriate damping adjustments on your coilovers to get the most out of the improved spring characteristics.
