What does a linear spring rate mean?

A linear spring rate means that the force exerted by the spring increases proportionally with its compression. This offers predictable suspension behavior, which is beneficial for performance tuning.

What is the inner diameter of this spring?

This spring has an inner diameter of 61mm. This is a common size for many performance coilover systems.

What is the purpose of a race spring?

Race springs are designed for performance applications where precise handling and consistent suspension response are critical. They often feature specific spring rates and lengths to optimize a vehicle's setup for track use or spirited driving.

About this part

Product Details

AST is known for making well-built suspension components, and these Linear Race Springs are no exception. This specific spring measures 300mm in length with a spring rate of 120 N/mm and a 61mm inner diameter. These dimensions are crucial for tuning your suspension for track or performance driving.

The linear spring rate means that as the spring compresses, the force increases proportionally. This predictable behavior is favored by racers and serious performance enthusiasts for consistent handling and feedback. The 61mm inner diameter is a common size for many performance coilovers, making it a versatile option for custom builds or replacements.

When building or rebuilding a coilover setup, choosing the right spring rate is key to achieving your desired ride and handling characteristics. These springs offer a solid option for those looking to fine-tune their vehicle's suspension for improved performance.
